I have a P5WD2-E Premium montherboard with default settings and no overclocking, but when I run 3DMark2006 or Aquamark3 after about 1 minute of running the whole PC restarts. Also I tried disabling crossfire in Catalyst Control Center and it does, then I try 3DMark2006 or Aquamark3 and everything is fine WTF??!! It's only when crossfire is enabled I have this problem. Does anyone know if there's any settings in the BIOS on a ASUS P5WD2-E Premium that I need to set? The Master card is in the blue primary slot and the slave is in the black slot, I check the cables are connected right just like in the pictures everywhere. I heard of people having problems too at this thread http://www.xtremesystems.org/forums/...sfire+settings

Some had to set the two slots to 8x, but I don't see that option in the BIOS at all. Or is there some settings I should have on in Catalyst Control Center under the 3D stuff?? I read that message about turning Catalyst A.I on when using crossfire and I did that, but still having problems
Please is there anyone out there that knows what's going on here?? Thx
