Added another GPU for the Chimp Challenge, but now my slots are all messed up. What to do? - Page 2

Perhaps its the drivers? What are you using now? I know that some drivers work better than others.

Also, just to see if everything is working properly, do your cards load up fine in games? I'm thinking you can try setting up your 9800GT as a PhysX card, then try running FluidMark (PhysX benchmark) to see if all your cards are being utilized properly. If you want to try it, be sure to get version 1.3.1 of FluidMark, as that's the only one that supports SLI/Crossfire.

I'm using 290.53.

I found that the gt9800 works on its own in both the x16 and x4 slots on the motherboard and it's folding just fine in an x4 right now. I'm going to try adding in the gtx460s one at a time and if adding one works, but the second doesn't, then I'll conclude that the PSU isn't enough of a PSU.

I'll try your suggestion. I did have them running Borderlands today, but I don't think that uses PhysX.

Thanks or the reply.

I ruled out the possibility of the cause being a lack of power. The GT9800 wont fold with a gtx460 in the first x16 slot. Any ideas? I want to make the most of this Chimp Challenge!

Hmm, well I'm stumped. redface.gif

I've heard elsewhere that the 290.53 drivers are the ones to go with for folding, so I don't think its that. And my thoughts are that a 750W PSU should be able to power all three cards fine as well.

My only suggestion is to keep swapping around the cards until you find a combination that works. Hopefully someone more knowledgeable will stop by with more info.
