GTX 260 as main GPU, GTX 580 folding

post #1 of 7
Thread Starter 
Hey everyone,

Since I got my GTX 580 I've had it in my PC folding away with my GTX 260 sitting happily alongside it doing absolutely nothing. I decided I wanted to swap their places, having the GTX 260 as my main GPU and the GTX 580 in the "PhysX" spot, for lack of a better word. This leaves my 260 open for gaming so my 580 can happily fold away 24/7 without having to pause it to game.
Unfortunately the GPU3 client that I'm using is directing the work to the 260 instead of the 580.
How can I tell the GPU client to use the 580 instead of the 260 in this configuration?

You have to add the correct flags depending on the slots, in your case it would be...

-gpu 0 for the 260
-gpu 1 for the 580

How to add flags

Awesome, thank you!
Do you think the way I have it set up is bad? Am I missing out on some points by not having the 580 as my main GPU? My motherboard is x16/x16/x1 so I don't think it would make a difference, just thought I'd ask.

Nope, bandwidth isn't an issue when it comes to folding and either way both your slots are x16 so its fine.
I know your not the first to do it that way.

If you play games like Crysis Warhead, I don't know why you'd want to use your 260 over the 580.

I have one more question if you don't mind. You seem to be quite knowledgeable so I want to take advantage of you while you're here.

I occasionally want to fold with my 260 as well. I read through the Multi-GPU guide, but it seemed to deal more with two identical cards in SLI. Considering the 260 would need to run the GPU2 client and the 580 would need to run the GPU3 client, would I need to download and run the two different versions?

The 580 is mine temporarily, as I'm planning on giving it to a friend. I don't want to get too used to it now.

Its easier to run two different clients, cause sometimes having GPU3 on non Fermi cards can cause an issue. I haven't heard it popping up much lately but before it was a concern.

Trial and error is all I can say but PPD will basically be the same.
