I had a lot of problems with this new board, but that was partially my fault. I hadnt given the ram enough voltage, and it was blue screening after a few minutes. It seems to be running Ok for now, but it doesnt recognize my raid every now and then, and I have to reboot a few times to get it to go. Also, at stock voltages my temperatures seem higher. This could be because my AS5 hasnt cured yet, but this is probably the most unfortunate thing to come from this board. It could be the 603 bios as well, but Im going to let it sit a while with this bios. It caused me too much grief the first day I put it in, that Id like it to work well for a few weeks, maybe start folding again
