After I've run Prime95 for a while, I'll try flashing to the newest BIOS and also dropping my FSB term and CPU GTL Ref settings. Right now, both my CPU vCore and FSB Term are 1.225. I wasn't aware of the fact that FSB term should be no higher than vCore. Should I be taking vdroop into account at all? According to CPU-Z, my vCore is at 1.160v to 1.168v, which seems very low.

What 790i board are you using? The P7N2?
