What I did for the time being is switch it to "mode 1" on restart. I know this isn't exactly recommended, but for minor changes, (ie enabling/disabling lan, onboard sound, boot order etc...) it seems alright. I have already made all the important changes (cpu speed, overclock, etc..) and am back to normal restarts and all is well.

I just installed and played COD4 for a few, just to test 3d stability and everything seems to be working just fine. So far, so good. Tomorrow will be the big test when I take out my 8800gt and install the 2 HD3850's.

Another side note, 8gig of G-Skill is working flawlessly in this board, as it did with the P35-TR2. Just wanted to throw that out there...
