Mining pr0n

[znort987]

Here's a bit of real mining pr0n:

CAD model before building the real thing:



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



And here's the real thing (slightly uglier, but
hey, reality is never as clean as cyberspace):

Front:


Back:


And here's the thing running cgminer:

Code:

Even if bitcoin value falls to zero, the fun I've had
building one of these things will _not_ fade away  

[stryker]

very nice !

[caston]

I like this a lot. What did you use for the frame and for securing the motherboard in place?

[Graet]

impressive!
good work

[Dargo]

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.

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  

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.

[Reckman]

Imo add some fans, close off the top, sides, and front except for an area around gpus

[SlaveInDebt]

Great efficiency!

[CA Coins]

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.   

[ngzhang]

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?

[AssemblY]

Very good! 

What motherboard are you using? And the risers are 16x to 16x or another?

Congratulations for the project!

[AssemblY]

Very good! 

What motherboard are you using?

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?

[wormbog]

Did you create the CAD model of that motherboard with all the capacitors and whatnot?

[AssemblY]

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? 

[AssemblY]

...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

In case this is helpful for someone reading this thread, here is a useful link on mobos:

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.

Hardware specs?
