Ya it seems I have stumped upon a problem that many others have been having. For folding@home you want to run w/ NUMA disabled as we get a significant decrease in the time it takes to press a frame. So naturally I run w/ NUMA disabled. But when I bought a second HD6950 it wouldn't boot with NUMA disabled. No matter what clockspeeds/voltages I tried. It seems other people on [h] have had issues w/ disabling NUMA but didn't know that the second videocard they had was preventing it. However there are people running 3/4 videocards but not having this problem.

In other news, my E5645 SR-2 system is being a . On their own each CPU is stable. If I enable both CPUs it is completely unstable. Please don't tell me I need to RMA another one of these boards.
