Now, unless I leave the BIOS at "Optimized Defaults" I simply cannot get an overclock on my rig without my machine entering a reboot loop and defaulting itself automatically back to stock settings. I have been waiting for the magic BIOS update to cure my troubles... and have been using QFlash for every flash since (I'm now at 6a), but still to no avail. My rig simply wont accept any even minor bump to any setting without entering a reboot loop and resetting to default settings.

I just reseated my chip on the weekend just in case as previous posters described bent pins (I didn't have any), but reseating it didn't make any difference. Does anyone have any ideas? (aside from ever using @BIOS ever again)?

I had a similar problem first time I flashed my bios (using QFlash) - had to set my memory multiplier to 6x otherwise I couldn't get over 150MHz
