I'll be working on a research project with the integrated use of multiple GPUs. I'm thinking of setting up a Desktop with multiple GPU first.

I currently have a MSI P55 CD53 motherboard, with Intel I5-570 CPU and Nvidia GTS 250 GPU. I want to buy at least another 2 Nvidia Graphic Card to add to my existing desktop.

Is there any resource I can lookup, so that I can know if it's feasible to do, and what Graphic Card I should buy?

Thanks a lot.

  • Why not look at Amazon's EC2 GPU offerings? I needed to try out a multiple GPU setup, and got one up and running to test for a few evenings without having to shell out for two Tesla GPUs. – lmortenson Mar 12 '13 at 22:37

The specification you linked indicates:

• 1 PCI Express gen2 x16 slots

That means it can only accommodate one PCI Express GPU at a time. So it's not feasible to run more than one GPU on that motherboard.

Questions like this are probably better suited to other forums like superuser.

  • Hi pls forgive me if I'm asking something sily... what does it mean by "1 PCI Express gen2 x16 slots" and "3 PCI Express gen2 x1 slots"? what's the meaning of *16 slots? or where I can get related information on these kind of terminology? – songyy Mar 12 '13 at 20:24
  • Well, when I used google, I got [this](http://www.hardwaresecrets.com/article/Everything-You-Need-to-Know-About-the-PCI-Express/190/4). – Robert Crovella Mar 12 '13 at 20:34
  • IC Thx. Hmm.. I also tried doing google but don't know what keyword to put. Google is more friendly to you I guess ;) – songyy Mar 12 '13 at 21:36
  • Additionally... do you think it's feasible to install an PCI-E X1 Graphic Card referring to: http://www.pcadvisor.co.uk/how-to/pc-upgrades/3360487/can-i-use-pci-express-x1-slot-for-graphics-card/ – songyy Mar 12 '13 at 21:46
  • It may be possible to do. I wouldn't recommend it. – Robert Crovella Mar 12 '13 at 21:50
