I just added a second MSI 660 ti PE to my rig, both cards work fine by themselves, but when I enable sli it locks up within a second of starting a game. When I run EVGA Scanner only one GPU is working, I have uninstalled and reinstalled the driver, removed and replaced the cards, I am fairly sure it is a driver or configuration issue rather than a hardware issue, both cards work and I flashed the bios on one card so they match. Any help would be appreciated.

I know you tested each of the cards, but did you test each of the cards in both slots? Just something else to rule out.

the bios versions were different on the two cards, I had to flash one of them so the speeds would be the same
