From what I've read I don't think anyone has used a multimeter on a P5Q-E to confirm overvoltage or not, but I'd say it's fairly safe to assume it does based on similarity to the P5Q deluxe and the fact that VCore overvolts.

But regardless, if I set everything to "stock" or "auto", in most cases those values are the minimum the board allows (e.g. 1.80V for RAM). If the board then overvolts beyond that, there's nothing much I can do about that.

Anyway back to my RAM problem, I tried 0704 and 0803 official bios but neither would even post using my old O.C. profile, so I didn't bother to try and reduce my overclock to make it I just flashed back to 1101. I seemed to have gotten good overclocks from that bios, and now that I'm in single channel mode maybe I can push the chip a little further (I was reaching an OC hole around 380 fsb before). I put in an RMA request for my ram on NCIX, so I'll wait to hear from them.
