Looking to build a GPU farm

post #1 of 7
Thread Starter 
I'm going to be building a GPU farm for bitcoining, likely out of 5850's, and I'm trying to find out exactly what configuration would be most efficient from an initial cost standpoint - 2 GPUs/rig, 3 GPUs/rig or 4 GPUs/rig.

I've configured an AM3 2 GPU rig for $251, and an AM3 4 GPU rig for $397, but I'm not sure that AMD is the best platform for the project. There's only 2 AMD motherboards that support 4 PCIe x16 slots, and not many more than support 3 PCIe slots. This leads me to believe that 3-4 GPU's is either not supported well on the AM3 architecture, or that Intel is a better platform for it for other reasons.

Would this board run 4 GPU's without a problem? http://www.newegg.com/Product/Product.aspx?Item=N82E16813138193

It doesn't need much bandwidth (a 1x slot would suffice), I just want to know if it works properly, and why there are so few motherboards to choose from that have 3-4 PCIe x16 slots.

Also, if anyone wants to config me a 3 GPU base rig on the cheap, I'd appreciate it. smile.gif

maybe consider going with an older 775 setup, or a 1156 setup.

Few boards from both provide 4 pcie, and some in fact have more, but require pci-e extenders. If your going to be buying everything, then might as well leave the option for more gpu's in the future.

Looking at Intel, there's only 14 boards that support 4 PCIe x16 slots. Interesting... I just thought there was a lot more support for 4 video card slots on a board than there really is. There's an ASUS 1156 board with 5 PCI x16 slots, but it would require an extender to use the 5th. And it's $189, which would increase the build cost to about $440. Plus, the difference in processor cost ($40 to $100) would bring it to $500. That'd be the same cost as building two cheaper AMD Sempron-based systems that supported 2 cards.

I guess the question now is, how does a 3-GPU system compare?

All of these would allow all slots to be populated with 4 GPU's

My vote goes to the MSI in that link

If you are looking to save money... I have found some 790FX boards for cheap... some on ebay others at Fry's on clearance. I picked up my MSI 790FX for $60 brand new. (with 4 x16 slots)

Lol, not looking to rape myself with prices! This IS just a farm machine, I don't need anything special as long as it works.

Nice! I don't have a Fry's very near me (2 hr drive), but I'm definitely on the lookout for good deals. We'll see. smile.gif
