Yeah no problem. I'm priming with the final bios now to see how things go. I've had the board do this to me before too, but then I finally managed to stabilize things, and it was rock stable for around 8 months. In my experience the board can be a bit quirky from time to time. And it doesn't seem to like my new 4870x2 either. Ah well, if I can't get things to work the way I want I may get one of those Biostar Tpower P45 boards to test. Would be fun to get something new anyway.
