Title: Mining pr0n Post by: znort987 on September 11, 2011, 02:25:40 PM Here's a bit of real mining pr0n:
CAD model before building the real thing: http://i1090.photobucket.com/albums/i365/znort987/3.png That's: - 4 5970s (8 cores) - GPUs are powered through an external 12V rail instead of the PCI-e - paired-up dual PSUs - sucks 1120 Watts at the wall socket - runs at 3009 MH/s steady 8) And here's the real thing (slightly uglier, but hey, reality is never as clean as cyberspace): Front: http://i1090.photobucket.com/albums/i365/znort987/r2.png Back: http://i1090.photobucket.com/albums/i365/znort987/r1.png And here's the thing running cgminer: Code: cgminer version 2.0.0 - Started: [2011-09-07 10:59:38] Even if bitcoin value falls to zero, the fun I've had building one of these things will _not_ fade away ;D Title: Re: Mining pr0n Post by: stryker on September 11, 2011, 02:33:29 PM very nice !
Title: Re: Mining pr0n Post by: caston on September 11, 2011, 02:36:56 PM I like this a lot. What did you use for the frame and for securing the motherboard in place?
Title: Re: Mining pr0n Post by: Graet on September 11, 2011, 03:58:12 PM impressive!
good work :D Title: Re: Mining pr0n Post by: Dargo on September 11, 2011, 05:19:27 PM Sweet rig, very cool. But at current bitcoin prices it's a little like looking at pictures of a hot girl who you know has syphilis. :P
Title: Re: Mining pr0n Post by: Dargo on September 11, 2011, 05:35:20 PM Sweet rig, very cool. But at current bitcoin prices it's a little like looking at pictures of a hot girl who you know has syphilis. :P LOL, this has all been paid for upteen times a long time ago by horrible little rigs built out of ebay refuse, crowding my kitchen an running on top of Mobo cardbox boxes, so who cares about the building costs ;D Also, at the risk of going off-topic, the whole bitcoin community is so short-term focused it's just sad to watch. Typical american approach to doing things ::) Who cares if the price drops further to even a 100th of a euro ? In what way does that diminish the intrinsic usefulness of the system ? The only thing I worry about is volatility as this will in effect prevent legit businesses to adopt the tool because the usefulness of the system is offset by the currency exchange risk. As to the exchange rate itself, it can bloody well settle wherever it wants, who cares ? Finally, as to the cost of power - I'll just say this: this is what will separate the men from the boys in the long run: FPGAs will kill GPUs first, and then ASICs will kill FPGAs. Yeah, it was just a joke. It's cool that your rig is already paid for several times over (makes it sexier), and I totally agree with your other points. Title: Re: Mining pr0n Post by: Reckman on September 11, 2011, 11:41:33 PM Imo add some fans, close off the top, sides, and front except for an area around gpus
Title: Re: Mining pr0n Post by: SlaveInDebt on September 12, 2011, 01:00:41 AM Great efficiency!
Title: Re: Mining pr0n Post by: CA Coins on September 12, 2011, 02:44:10 AM Sweet rig!
I agree with you. I find BTC very useful, especially for all-digital exchange of goods/services. Mining might not be profitable in the short-term, but it has a future. :) Title: Re: Mining pr0n Post by: ngzhang on September 12, 2011, 01:24:27 PM hi, znort987. Are you interested in FPGA mining systems? If so, at least how much MH/s pre $ will let you determine to buy them?
Title: Re: Mining pr0n Post by: AssemblY on September 12, 2011, 02:29:56 PM Very good! :D
What motherboard are you using? And the risers are 16x to 16x or another? Congratulations for the project! Title: Re: Mining pr0n Post by: AssemblY on September 12, 2011, 06:45:57 PM Very good! :D What motherboard are you using? Quote And the risers are 16x to 16x or another? Three 16x to 16x and one 8x to 16x. I tried a 1x to 16x but it didn't work, and I'm lazy/weary to solder on a mobo , so I didn't try the slot shorting trick for the remaining 1x leftover slot. Right! But, what is the model of this motherboard? Title: Re: Mining pr0n Post by: wormbog on September 14, 2011, 09:50:16 PM Did you create the CAD model of that motherboard with all the capacitors and whatnot?
Title: Re: Mining pr0n Post by: AssemblY on September 16, 2011, 01:12:41 PM Did you create the CAD model of that motherboard with all the capacitors and whatnot? Nope. Another forum member suggested the Google sketchup community site (3dwarehouse) and I found tons of PC parts all set and ready to go (including textures :) ) By the way, anyone interested in the CAD model can have them for BTC 1 in blender format (I can also probably produce other format, but YMMV). ...and the model of motherboard, can tell me? ;) Title: Re: Mining pr0n Post by: AssemblY on September 16, 2011, 02:25:50 PM ...and the model of motherboard, can tell me? ;) The mobo I'm using is absolutely _not_ something you want to use to build a rig: t'is expensive and only accepts high-end Intel CPU's which are _also_ expensive. Absolutely not a good pick from a monetary POV (I was just very lucky and picked the combo on the very cheap on ebay) Anyways ... if you really must know: Mobo: Gigabyte EX58-UD5 Processor: Intel Core i7 960 @ 3.20GHz I'd search these forums for better Mobo for a rig (something that will have 4 x16 PCI-e and remain cheap). I know, I just wanted to know the model of curiosity. I use Asus Crosshair Extreme Iv. thanks for answering ;) Title: Re: Mining pr0n Post by: Dargo on September 16, 2011, 02:46:54 PM ...and the model of motherboard, can tell me? ;) The mobo I'm using is absolutely _not_ something you want to use to build a rig: t'is expensive and only accepts high-end Intel CPU's which are _also_ expensive.

In case this is helpful for someone reading this thread, here is a useful link on mobos: https://bitcointalk.org/index.php?topic=37880.0 I can personally vouch for the Biostar A870U3 - great cheap board for mining ($65 from Newegg). Has 2 x16 PCIE slots, 2 x1 PCIE slots and works great with risers.

I used sketchup to make a model of a case I was considering, the 3D warehouse is amazing. A friend of mine does a lot of 3D printing, and he swears by it.

I can't find them anywhere!
-EP Title: Re: Mining pr0n Post by: turquoise9955 on September 18, 2011, 06:14:36 AM looks great!
Title: Re: Mining pr0n Post by: worldinacoin on September 18, 2011, 06:18:09 AM Yours a real beauty, something I really hope to built but do not have such mechanical skills. Maybe my next rig I will try to do something like that
Title: Re: Mining pr0n Post by: EPiSKiNG on September 18, 2011, 10:56:25 PM What kind of cooler did you use for that 5970?? I can't find them anywhere! -EP The one 5970 that has a different cooler ? It's an Arctic Cooling "5970 arctic accelero xtreme" I just picked the card on EBay with it, it's not really useful except if noise levels are something you care about (it's much more silent than stock turbine). You don't get cooler temps? With the Arctic Accelero Xtreme 5870 that I have on two of my 5870s, I saw a dramatic decrease in temps.. (from 80s to 50s). No such luck with the 5970 then eh? -EP Title: Re: Mining pr0n Post by: jjiimm_64 on September 19, 2011, 07:53:24 PM the stock cooling solution does well enough. I am running 3 of these cards in a 8 gpu rig. They run much cooler then I expected. if memory serves, I clock them at 880/440 set the fan at 60% and they stay in the low 70's.. 71, 73 Title: Re: Mining pr0n Post by: jjiimm_64 on September 20, 2011, 01:47:44 AM "8 gpu rig" that would be 8 cores. 3x5890, 1x5870, 1x6950 getting about 2.9Gig |
