I'm using the lates driver. I bagn to use the sli system for a couple of wekks ago with no problem with FEAR and Fra CRY and 3dmark 06.
BUty yesterday, Sli made some errors. When i started FEAR or Far CRY the picture was all bad, and a lot of colors....when i disable sli everything works fine.
Somebody hav an ide, what it could be?

You might get more help if you post this in the Video forum. Since the system works normally with SLI disabled (only using the first video card), I would suspect that the second card or second PCI-E slot has failed or is failing. Remove both cards from the system and put the second card in the primary PCI-E slot and see what happens. If it also works normally then try the other card in the second PCI-E slot and test the results.

If you get video corruption with the first card in the second slot, then you may have a problem with the second PCI-E slot on the motherboard.

If the system works normally with both cards running separately in either slot then the problem would have to be with the SLI setup itself and I'm afraid I can't help you much there since I don't have any experience working with SLI beyond basic troubleshooting.
