Good to know. Using the same BIOS too. Seems to be fine booting into 460FSB (3.9GHz) with these lower settings you've given me. Gone through 15 passes of linpack64 so far and holding.
I appreciate I can't get the 4GHz on this, but 3.9GHz on lower volts is good thing. Is the damage I caused gonna keep getting worse or will it slow down now that I eased off?
