I'm going to test max FSB, I got 420FSB stable easy (110% OC). I tried 430FSB, I walked away to get a drink while it was booting, then next thing I know the PC and phase change turned off
I'll give it another go soon.
EDIT: Dam, after 425FSB I hit a brick wall
Oh well I guess that is a 125.5% FSB overclock - not bad.
EDIT 2: OMG I just realized i'v been using the crap BIOS, WTF my board flashed itself back to the old one.
