My Q9450 has never been stable unless I underclocked it. I even tried the lowest voltage 2801 allows as a manual setting (1.45V I guess) and that also rebooted on me. I guess it's not insufficient voltage like I thought. Since the latest BIOS hasn't been reported to make a difference I haven't bothered with it.

I still see ASUS pulling a too-many-defects-deny-everything on the 1.02G problem. To tell me that NOBODY ever sent back a 1.02G with the kinds of complaints we have is hard to believe. I just toughed it out rather than be without a PC for a month, but I can't see everybody being that willing to put up with junk. Must be they ran out of bad boards before the hard-to-please types got theirs, or another reason for the returns was going on...
