5 Best USB Bitcoin Miners 2020 – Reviews & Buying Guide
external case with its own psu
Hi, I recently got an hp dl380p g8 server and wanted to use it to upgrade my old rig. I want to use all my disks, and since I'm already using a sas expander I though that I might keep the old pc case with the psu and all the disks, put a 5v arduino relay module connected to a usb port of the server, to short to ground the green pin of the psu when powered on, and connect the sas expander to the new server's hba card that I'll move from the old. I wonder if it is safe to do so, both devices will share the same ground, but they'll interconnect through minisas internal port, not external sas ports that are designed for that, my hba doesn't have external sas ports by the way. Other people use dual psu setups on gaming rigs or bitcoin miners without issue. I've seen minisas to external sas adapters, but it seems that they only change the connector format, no chips onboard to electrically isolate, there are also cables with external sas/mini sas ends. Kind regards.
Going to build a new high-end PC, for gaming, video editing and other heavy workloads. I already have an AMD 5600XT GPU, and a CM750 PSU that are a few years old, but used only a little when I had it powering bitcoin miners for a year. I have a 1TB Crucial SSD for secondary storage I have ordered, but not yet picked up:
i7-10700K + Arctic Freezer 34 eSPORT fan (listed 200W TDP). Not sure if it is worth it over non-K. Non-K supposedly throttles down after 56 seconds. Avoiding/minimizing the LP1 throttling is my main concern. Are the K series really better ? Tested for running at higher speeds ? Or is it same quality ? Water cooling not really something I want, unless it is really worth it. My experiences many years ago were not that great.
Z490 Motherboard, MSI Tomahawk, as I want high speed USB-C. non-Z490 are hard to find, a few available in mini-ITX form factor. So decided to pay the $100 extra.
Fractal Design Focus G case - Good or bad ?
A-data 8200SX Pro NVMe
Corsair Vengeance LPX DDR4-3200 C16 BK DC - 32GB. It might be overkill with 32GB
Any bad choices here ? I try to keep it cheap, but pay a little extra when I think it is worth it. Should I use my old PSU ? Or get a new 550W Gold rated instead ? CPU + GPU = <400W at max load. So 550W supposedly most efficient (run at 65-80% of PSU capacity is most efficient from what I read).
I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!
Requirements: 1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does. **Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc* So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though. After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there. Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly). I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01 Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!! -----How To Do This Yourself: Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money. Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses. Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!) Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!! https://cryptotabbrowser.com/8557319 Links to Picture Proof http://imgur.com/gallery/P13bEsB
I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build).

CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)
Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.) I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards. Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/ (I was also leaning towards the DE1-SoC.) Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018. I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs) Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not. EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard. UPDATE: I've put together a table with some of the best options:
A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.
icoBoard ($100). (Buy it here.) The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.) The icoBoard also supports a huge range of pluggable pmod accessories:
numato Mimas A7 ($149). An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)
What can I do with an FPGA? / How many LUTs do I need?
VexRiscv is "A FPGA friendly 32 bit RISC-V CPU implementation." This is a RISC-V implementation written in SpinalHDL. VexRiscv has a lot of plugin and configuration options. The Murax SoC is a very light SoC that can run on an iCE40-HX8k (but probably not the 1k FPGA that only has 1,280 LUTs). The Briey SoC only runs on Xilinx or Altera FPGAs.
Jihan Wu: "blocksize is a minor issue that cost the community so much damage. It has given too much opportunities for some people who are altcoin developers. We have more challenge to solve, for the future of Bitcoin rather than a blocksize thing."
Jihan_Bitmain full quote : "Hi I am fine. Thank you. I am pretty busy after the U.S. trip, and I don't have the time and mood to talk on the social media right now. But I read on btc and bitcoin. BIP109 is a compromise. They want to reach something by compromising, but it will not work. 2MB cap would bring us trouble in less than 1 year if it is selected by miners. I don't think I will vote for BIP109. We need a plan that will not drag the community into the blocksize issue from now on. For the growth of Bitcoin, blocksize is a minor issue that cost the community so much damage. It has given too much opportunities for some people who are altcoin developers but also claiming to be Bitcoin reference client software developers. We have more challenge to solve, for the future of Bitcoin rather than a blocksize thing. Bitcoin has a very long way to go to be a world reserve currency. I think everyone reading this post should buy a mini PC, like Intel NUC, in his home, with 500G-1TB disk and wifi. It cost less than 500$. It is running a full node, so don't go extreme to try to run it on a 10$ worth second handed RasPi. It will be able to support the network for at least 2-3 years. By adding HDD on the USB port and some pruning, it will be lasting even longer. You can express your point of view by running a certain kind of full node you like. It will be much more cheap and stable than running in VPS in the long term."
The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
A Raspberry Pi. You can do a lot with this. One thing you can't do, however, is reliably run a Bitcoin node: the single gigabyte of RAM gets crowded with the bitcoin memory pool (normally up to 100 megabytes, or more when a "stress test" is taking place).
A 128 GB micro-SD card. Used to store the block chain, which is about 32 gigabytes in size right now, and growing at about 144 megabytes per day. Unfortunately, the copy of the block chain 21 Inc. includes is obsolete the second they ship the product, so you have to wait a few hours for the block chain to synchronize. This uses those valuable limited write cycles you have on your SD card.
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)
Is that all I get for my money?
Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:
An ASIC chip and a giant fan. Bitcoin mining hardware has a propensity for running hot, so you need a fan. Unfortunately, the Raspberry Pi can't power those two items. The Pi uses a standard 5 volt mini-USB connector for power, and draws at most 2 amps. The fan alone uses three times the maximum current that the Raspberry Pi can handle. Also, a tiny fan like this emits lots of noise, so you may want to include some earplugs in your Amazon.com shopping cart. Free up another outlet for you to use, because there are two power supplies!
It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:
Web proxies, but with bitcoin! Gone are the days where you would pay a small fee (normally, no more than $9 per month) to access a wide array of private proxies. Now you can build your own service where you charge customers 1 cent per request to use a single public proxy. If that doesn't seem absurd yet, consider the following: loading this page probably used 60 requests for images, fonts, and various code to make the page work.
Online SMS gateways, but with bitcoin! Don't pay your phone company fifteen cents to send a single short message, and definitely don't pay a monthly fee to send unlimited messages! Be your own phone company and lure people into using your gateway. Granted, developers can use the same third-party messaging API for free, but that isn't the bitcoin way. Also, you may want to make sure you're legally a company and not an individual, just in case people want to use your message service for sending death threats to those who defame Satoshi and a few three-letter agencies charge you as being responsible.
Is there any benefit to building your own desktop with the current prices?
So I have been trying to finalize a build set up for the past few months. Prices have been skyrocketing lately due to the bitcoin miners. My question is, what is the benefit of actually building your own pc right now? For reference, I have found an overall great pc at best buy. I don't think it would be possible to build this pc myself for any cheaper. My build: PCPartPicker part list / Price breakdown by merchant
Minted our first bitcoin this morning! Took about 18 hours (Butterfly Labs Mini Rig SC 500 GH/s)
http://i.imgur.com/LvDPIjY.png We're using the Butterfly Labs 500 GH/s Mini Rig. Might as well do a small review -- the hardware itself is temperamental. For example, ours showed up with the unresponsive Nexus tablet on the front panel. Dealing with Butterfly is a total shit sandwich given the rip-and-run state of the overall business, so I had to figure out how to bypass the internal routing and have a laptop be the brains of the operation. After a couple of days of messing with usb drivers, which refused to stand up on Windows 7, I finally got the laptop to recognize all 8 modules. However, I could not start mining due to an error starting the bfg miner task from the inside of their Easy Miner application. I tried to force bfg via the command line, and it finally worked, although the hash rate was atrocious. Another day or so, and I had the rig mining. The hardware recognition issue was due to me not giving the laptop enough time to kick ALL modules on. It takes a good 2-3 minutes for all usb notifications to stop bleep-blooping. The hash rate was in the 470 GH/s area, which was perfect, but then the modules started to shut themselves off due to overheating at 83 C. The log would show how the unit was taking down hot modules and then kicking them back on non-stop. The ambient temp in the room is around 75. I played with positioning, fan speeds, to no avail. The hash rate at that point dropped into the 400s, and my 15 amp circuit breakers started to get tripped. This went on for a little, and then I permanently blew one of them and had to pick some up at the Home Depot. But hey, it only took a single trip :) So then I got a 5200 BTU A/C unit, mounted it in the window, and positioned the rig in front of it. That seemed to fix the breaker-tripping and overheating issues. It runs at low 70s C during the day and low 60s C at night. I am now making custom funnels out of thermal foam board to vent exhaust heat outside and also connect the 11" AC opening to the 16"x16" intake area of the rig (looks something like this). The unit generates a lot of heat, no joke. I bet when the weather gets colder, it can serve as a furnace for this side of the house. If you're wondering why I'm talking about it still not being cold outside in November, I'm in Texas. It's really beautiful right now, high of 75 and sunny. Also, the noise ... how could I forget about the noise. It sounds like a server room. There's 18 fans, plus PSU fans, and they are quite loud. Don't expect to inconspicuously set this rig in the corner of your living room. It's been on for over 24 hours now, uninterrupted. To the moon!

The $22,484.00 Butterfly Labs Mini Rig bitcoin miner is a huge, broken, unstable piece of shit.
(This was a rather controversial article posted on Buttcoin.org and became quite popular, even moving to the top of /bitcoin. It's since been mysteriously edited on the site [maybe by g-g-g-ghosts!] so it's being reposted here for posterity's sake. Some numbers may be off by now, but it was all accurate at the time of posting.) Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5. So what does $22,484 buy you? Take a look!
Minirig is here! Today, my Minirig arrived. http://i.imgur.com/Yp0WPvE.jpg FedEx apparently dropped it somewhere along the way, and the weakest part of the case, the thin metal part around the back of the PSU, broke. http://i.imgur.com/lFcOHxP.jpg I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either. http://i.imgur.com/AVttcOt.jpg The power supplies (EVGA 1500W) also created havoc interfering with the neutral on the power line. This disrupted X10 communication significantly enough that the pool overflowed because the system controlling it was unable to turn off the pump. Workaround: This PSU supports 240V, so we rewired the outlet. 240V does not use neutral, so now all should be okay. Edit: 240V workaround is only partial. Still having problems But the good news is, it all seems to be working for the most part. Next up, installing it in the window so the heat goes outside
A twenty two thousand dollar box of electronics that is broken out of the box, that required the guy to do a sketchy electrical workaround to get partially working, that he is going to install in a window… and he’s happy about it? In case you didn’t notice it, the delivered unit is different than the picture on the website. They had to install 2 power supplies instead of 1 and had to modify the case to fit. Also, if you didn’t notice, the LCD/Phone thingy in the front has been replaced by … a piece of cardboard spray painted black. Wonderful. You could maybe chalk this up to a careless Fedex postman, but when you’re shipping something that costs as much as a mid-sized sedan, how bought putting a little more effort into packing? Dell and HP can ship bigger and heavier servers across the world without this kind of problem. The unit had to hit its huge power draw increase by putting dual EVGA consumer grade power supplies in the unit. We’re talking almost a 75 amp load (6*1500/120), disregarding power factor. He could very well overload the circuit panel and trip the main breaker for the house. Let’s take a look inside this guy. This is from an earlier version of the Minirig (note the single power supply) This is apparently from an earlier FPGA but it will give you a good glimpse at what kind of craftsmanship you can expect from a computer that is half the average household income in the United States. Consumer grade PSU and cheap USB hubs glued to the inside case. Electrical tape and random velcro glued to the insides A closer look at the USB hubs. Plugs are hot glued to stay secured. Electrical tape everywhere, splices and voided hardware are the theme. You can view the entire album here. Despite all that, this thing can still mine bitcoins and it should be profitable. Keep in ind that many people jumped in on the preorders a year ago when bitcoins were still hovering around $6.50 per. Meaning customers paid 1562 bitcoins for that particular piece of shit, which at today’s value is $156,200. Aston martin money. How long will it take them to make their money back (as apposed to just hanging on to them)? If the difficulty didn’t change, they would make 37 bitcoins a day and recoup the initial investment in 124 days. Difficulty is jumping pretty much 20% every 12 days or so, so in the next week before adjustment, they’ll make 259, the next 12 days 369, the next 12 days 312, then 256, then 213, etc. So by day 127, they’ll be halfway to breaking even, but by day 151 they’ll be making less than 5 bitcoins a day, and even if difficulty stopped rising at that point(which it won’t), it would take another 435 days for a total of 586 days to break even. If difficulty kept rising at the same pace, by day 200 they’d be making 2.4 bitcoins per day, and it would take 1024 days to break even with no difficulty increase. Assuming 25 cents per kw/h, and $100 a bitcoin, it would cost 0.43 of a bitcoin per day in electricity which means the unit would no longer be profitable on a power usage basis by day 307, at which point it will have produced 2620 bitcoins. Bear in mind this is only for the first few units, and that’s running 24/7 pumping out around 24,000 BTU, so yes, medical bills from heat stroke will be on top of that. But Alas, the chips don’t run nearly as well as they’re supposed to, frequently running too hot and giving multiple hardware failures. Coindesk noted in one of the first ever runs of the Minirig by hosting provide gigavps that it was running much too hot and erroring out.
At the time of posting, gigavps warned that the unit would be repeatedly shut down while ckolivas, who was assisting, modified the machine’s software to optimise performance. After some tweaking, the device was said to have been left to run continuously for two hours, and was shown to have an average hash rate of 478.1 GH/s. As you can see in the table below, ASIC number four (of a total of eight hashing chips) ran significantly hotter (86 degrees) and consequently gave the highest hardware (HW) error rate. http://i.imgur.com/q3iGrnb.jpg
So, what happens if you just decide you don’t want this, you don’t want to wait over a year to get a $22,000 broken piece of shit? Nothing, because BFL won’t let you cancel your preorder because they’re now “shipping”, i.e. they sent out one unit to their own company shill. http://i.imgur.com/0p3Up03.jpg Which is of course illegal regardless of what Butterfly Labs may say. So in summary: Don’t buy anything from Butterfly Labs … ever.
Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it. https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg 1) Hardware List -Raspberry Pi Model B --SD Card --Micro USB power supply --Ethernet cable -Gridseed ASIC --12V power supply (5.5mm/2.5mm barrel connector) --USB to Mini USB data cable The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware. The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that. The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too. 2) Software If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be). Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software. Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now
Log back in with the pi user once the Raspberry Pi is finished rebooting. The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in. To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0
I took the plunge - 2x 7970's on their way for potential rig - I have no idea what I'm doing - Help appreciated!
So since this past Spring break, my brother in his all powerful insider knowledge on this strange thing named BitCoins introduced me to this bandwagon. I've since joined in and bought all I could muster with the funds in my bank without ruining myself and have thus far reaped a beautiful profit that my wife deems pleasant. This is, of course, something EXTRAORDINARY. Ahem. So I decided to wager my trust I've earned with her with said investment, and have decided to use a few more funds to build a mini miner. Obviously this won't be the mega tank that you see all over Youtube, Just a simple machine that may have the potential of 1.6GH/s is my hope. So this is what I've bought so far:
Total thus far after Rebates & Selling Games: ~$1300 USD Estimated 1.6GH/s with profits beginning in ~85 days (Before crash, of course XD - Now who knows!) Great thing is if all this goes kaput, I'll at least be able to resell it all! :D I have a monitor around for initial setup, and all the other obvious peripherals. What I am in need of are some tips or links in setting these 2 guys up. I'm somewhat new to Building a PCI-E Rig, but I'm sure its just as simple as plugging it all in, which I've done countless times before. I know that if I'm on Linux I won't need any dummy plugs for the DVI outputs on the other cards for it to be recognized by the OS. Can it be run purely all on a USB drive? That's one thing I'm a little unsure of. Mostly my questions consist of:
Physical Setup, if there's anything special about it all. Obviously I'll need some cooling going on. Would fan-cooling be sufficient? Or should I look into Watercooling? All I know is that if I do watercooling, I'll have to get specific water blocks for my cards.. But where to get them?
Any particular settings while using the miner program on linux to max out the performance on my 2x 7970's and 3x 7770's
Do you gain parts of bitcoins when you SoloMine, like you do in pooled mining? Or do you only reap a benefit when you hit a block of 25 bitcoins?
I don't care much for people bantering about how difficult it is now to mine, or how ineffective this might be, I've read my share about that. I plan on just having this run in the corner of my little apartment for a few months while I go to school/work/walk the dog/etc... I would like tips or any insider info on other fellow 7970'ers on how to maximize my performance with these two cards at my disposal. And of course those who do help me in my time of need and once it's all beautiful and vampiric-sparkly like will get Brownie Points in the afterlife. Last computer I built was back in 2004 so that I could play Half Life 2. And I was on a budget back then too. So I'm not too savvy with all this new cooling hardware and techniques as I've never had to deal with things that exceeded 4x AGP. I'll post pictures and videos of all the fun I have with this adventure :D Update Thus far I have only received my two 7970's and boy do they look beastly. I've never held a card that manly before. 2nd Update Everything came in! Goodness it's difficult to do a headless Linux Box! for sake of time, I think I'm just going to buy a cheap sata harddrive. 3rd Update So here's the final photo of it running with 2xx7970's I'm still waiting for the riser cables to come in to mount the other 3 cards. I haven't uploaded the videos of me building it all just yet (btw I sucked at putting it all together XD)
I just got this email: BFL Products Shipping Now May 1, 2013 Dear earcaraxe, Shipping of our BitForce SC ASIC miners has begun! You may have seen news reports of our ASIC miners in the wild and some of you may have already taken delivery. It's all true. We're finally shipping. You will receive your order as we work through the shipping queue . If you didn't know, you can check your order status on our website. Log in by clicking here. Use the same email and password you set up your account with. If you don't have your password, use the Lost Password function to create a new one. So what took so long? This third generation of our SHA256 engine was a complex multi-year investment in bringing the latest semiconductor technology to bitcoin mining. Developing a fully custom 65nm ASIC processor is not a casual undertaking. In fact, the new products have improved mining speed by a factor of 72. This much advancement doesn't come easy and it's fair to say that getting here has been eventful. The key issue has been the engineering related to accommodating larger power draws than expected. A good example is the Jalapeno product. It was originally designed to be powered by USB but now consumes the power of a small light bulb (30w). Consequently the power regulator, enclosure, airflow and PCB needed upgrading to suit. Although we are very aware of the undesirable dynamics of any delay, we were nonetheless obligated to make these updates in order to deliver a reliable product at the expected performance. The same adjustments have been made with all products in the lineup. You can see the adjusted product cases in our currently posted product lineup. (The Mini Rig case will be double shipped to satisfy their orders which is why we've run out Mini Rig enclosure stock). Final confirmation is required Please be advised that due to the adjustments described above, we need your confirmation prior to release of your order into the final build queue and on to final delivery. It may also be a good time to review your purchase altogether relative to the bitcoin market as this is the last opportunity to do so. If your order is not confirmed, it will be canceled and your money will be refunded. Thank you for your support and we wish you great satisfaction with your product!

Actually, I was an PCB board foreign trade salesman, working on alibaba platform for 3 years since graduated from university. However, about 6 months ago, I remembered that was an sunny afternoon, my boss(a really professional PCB、PCBA man) call me to had a cup of tea with him. “he must have some idea again” I know. Then I felt very nervous, praying he gave me some good news like increase salary for me or something similar, but not fire me. God bless me. He really share me an surprising product.- Bitcoin asicminer.
2013,9th, Sep BITCOIN ASICMINER, this new word then accompanied me for the last days till today. Since 2012, I have learned something about bitcoins from my friend. I know that [Bitcoin is a kind of network virtual currency, anyone in the world can use to purchase virtual items, such as clothes, hats, equipment in network game,etc. Certainly, you can also use bitcoins to purchase items in real life as long as the seller accept. However, the most special point for bitcoin is that the issue, circulation and management of bitcoins does not belong to any person, organization, company or any country. In another words, it’s equally and belong to everyone who participate in. Anyone who have a computer, connecting to network, and then running a free open source software can be involved. There is never such thing that anyone who as an administrator or who have the center node or privilege. That calls BITCOIN SYSTEM, a equally peer-to-peer(P2P) systems. Most important of all, BITCOIN SYSTEM can promise as below: 1. the total quantity of bitcoins is certained. 2.the quantity of bitcoins increase at a slow pace, but not sudden increase. 3. bitcoins will eventually increase to a certain quantity, but not unlimited growth. 4. the above characteristics are guaranteed by a recognized mathematical formula, do not need any guarantee come from any person, any organization or country. 5.the circulation of bitcoins do not need any intermediaries and the transfer process is not subject to interference]. So this news asicminer is a big surprise for me. At the first week, I was curious about this magical hardware , but then I nearly crazy about it. 2013,9th, Sep 13:46
As time by, we learn more and more(an crazy increase speed) people are interested in bitcoin,, either to be a miner mining or invest bitcoins. About half an month later, I was called to have a cup of tea again. This time, I was exciting. As expected, boss asked: If you want to sell bitcoin asicminer on aliexpress? My answer is YES, without any hesitation. Then my experience with bitcoin asicminer hardware begain……… Then our store--- China BTC Electronics Co.,LTD (http://www.aliexpress.com/store/340830) opened, our asicminer begain selling on aliexpress. At first, we selling 330MH/S USB asicminer, then we selling 10gh/s blade asicminer and till today, we add 10gh/s mini blade asicminer selling
Here want to share some experience with my customer. My first customer is an gentleman from Russian. I remembered it was about 16:00 on Monday, trandemanager pop up a message. He very nice to say hello to me and told me he came from Russian and was a newer very interested in bitcoins, want to try to have a USB block erupter, but wonder if we can teach he how to use and wonder if we can ship to him immediately. That’s absolutely what we should service for our customers. Then online we talked about how to use step by step, and I promised him when we confirm receiving his payment, we will arrange shipment in 24 hours. Half an hour later, he told me everything is ok. And pop up again, aliexpress notice me my customer place order and 1 minutes later, he paid the payment. I was so exciting. That was my first customer and so nice an communication process. Next day moring, I confirmed payment. WOW, before noon, I arrange the shipment. ……later, later, this customer feedback, it’s vey nice, and buy 5 units again. Considered he was my old customer, at that time, I gave him an discount. Haha, good experience!!!
Another very interesting customer from Brazil who is now become my friend. We always chat on skype, chat some latest news about bitcoin, bitcoin hardware. He is really an senior man for bitcoin.. I remembered that was midnight, I was in sleeping, and my trademanager on mobile phone pop up a message, which really scared me, you can image that in mindnight, and your mobile phone suddenly rang, how horrible a thing. “Customer is our God” I have to wake up. (Saleman is really working 24 hours.) Then he told me he want an 10gh/s hardware,but wander if we can help him make the invoice value smaller which is convenient for him to let custom clearance smoothly in Brazil. And hope we can ship to him in one week. 7 days later, he told me he received the asicminer form UPS and gave us a 100% positive feedback. Really thanks!!! What’s more, he introduced his friends to buy asicminers in my store(http://www.aliexpress.com/store/340830) Here thanks he again. And also thanks his friends trusting us.
At the moment I'm fielding offers for the entire mining rig. I will not be parting this out and will be selling at as one entire unit. I will pay for shipping. US only. Miners

2 13 Port Internal USB Hubs - Used to be sold by WTCR.
Current setup allows for 12 in each internal USB hub, 5 in each 7 port hub a max recommended of 9 for the two 10 port hubs. You can try pushing it with 1 more in each of the 13 porters and 1 more in each of the 7 port hubs but it isn't recommended. Based on that, there is room for 4 more usb miners recommended setup, and 8 if you want to push it. http://imgur.com/a/Rm5pf Please post an offer below. Going by current prices I'm looking for 8+ BTC. (Miners and Jalapeno alone at current prices around 7.8 BTC, .1 BTC per USB Miner and about 3 BTC (per ebay) for the Jalapeno) I know I won't be getting back what I paid for, but these are quality hubs and power supplies. I've also put this on Ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281182502521, but I would prefer to sell it for Bitcoin.
