Lockup with SLI, but single card no problem? - Page 2

The worst case scenario is that you will have to use this 280.26 instead of the 285.62. I do not think you cannot play BF3 and Batman Arkham City. The older driver is not optimized but it should still allow you to play through those games.

BTW, when you did the driver upgrade, how did you do it? What procedure did you use?
Thanks windfire, I tried the 280.xx and they did not work as well. I believe it was actually the 275.xx that I was using when it last worked. I will give those a try and see what happens, I was just under the impression that if I wasn't on 285.xx I wouldn't be able to load those games up. When I tried using the 275.xx on the beta back a few weeks ago, it would not let me play unless i installed the 285.xx and thats when i feel it all started happening.

When I install new drivers I uninstall the old one from add/remove programs then reboot in safe mode and wipe anything remaining with driversweeper. Then i reboot again normally and install the new drivers.

I'm beggining to wonder if it is my PSU that is causing it. I tried numerous different drivers and i'll either have 0.5 fps and/or lock up within a few minutes. I tried both cards induvidually and they both seem to handle it no problem. BIOS is showing my 12v as 11.8 which I assume is in spec and i dont have a spare PSU to try. Anyone have any suggestions?

I am still suspecting graphics card (hardware or software) related problem instead of PSU problem.

But regarding the PSU, make sure you are connecting the power cables properly from your HX1000 to the two GTX470 SOC.

Diagram 1 below is the preferred way for 2-way SLI (no difference between GTX470 and GTX570 in this regard). Two native fixed cables (12V2) connected to first card and two modular cables (12V1) connected to second card.

Diagram 2: not preferred for 2-way SLI as both cards are connected to 12V2. Better to spilt them up to 12V1 and 12V2.
Diagram 3: not recommended as native fixed cables and modular cables are mixed
