I have experienced the same as both camouflage and Sav. Earlier I posted that I have primed 7 h a 400x10 with LLC on Performance. Later it restarted during some file copying and was unable to boot to windows at the same settings.

Another thing that bothers me is that I have powered down, switched off the PSU and unpluged the cable - when I power up again I sometimes get a "CPU ratio something" error (press F1/F2). This can happen with CPU, FSB and RAM at default settings - no OC. Anybody else experiencing this? I hope I'm not running into another Striker II Extreme hell of inconsistency
