Help with configuration of 4 Tesla cards

Accelerated Computing CUDA CUDA Programming and Performance

I would really appreciate if knowledgeable people will comment on this configuration for a possible computer with 4 Tesla C2050 cards:

MotherBoard: Gigabyte GA-X58A-UD5 (it has 4 pci-e slots)
Processor: Intel core i7-950
RaM: 24GB (Corsair 6x4Gb DDR3 1600Mhz)
Video cards: 4 Tesla C2050
Power: Thermaltake 1500W

Thanks a lot!

You will only be able to use 3 C2050 with that board, not 4.

Thanks, which board would you recommend instead? Why is it that only 3 c2050s are supported on that board?

Asus Rampage III Extreme, will this work with 4 C2050s?

C2050s are double width cards. There is only room for three double width cards in x16 slots on that board (note two of the 4 x16 slots are next to one another on that board, so both can’t be used with double width cards).

Something like the Asus P6T7 WS SuperComputer board can theoretically take 4 C2050. I have no experience with it, however. You should keep in mind that if your application needs a lot of PCI-e bandwidth, that you won’t be able to achieve full host<->device bandwidth on all cards simultaneously in you are running more than 2 gpus on any Intel X58 board (or any AMD 790/890FX board either).

EDIT: yes the Asus Rampage III Extreme has the correct slot layout for 4 GPUs. Same caveats apply about bandwidth.
