*GameOver*: I'm jealous!! Looks like you have a VERY good chip there...

I know I tend to preach this piece of software a little, but running hours of Prime have already killed one of my Mobo's (PWM) and it didn't always relate to 100% stability even after hours of stress...

IntelBurnTest isn't perfect either, but a 1/2 hour run (5 loops) will give you a much better idea of wether your system is stable without killing your board....

Just a suggestion, but it's the only program I use for final stress testing anymore...

WOW!, just noticed your getting those clocks on an SB600 board.
Golden Chip man... Gratz...
