Exactly what I wanted to ask.
Same board, just Phenom II X2 550BE and 3g 800mhz. I unlocked the 2 dormant cores, Win 7 boots fine, sees the cpu as X4 B50 but Windows Experience Index crashes while testing (windows doesn't crash itself, just the Experience Index) haven't tested anything else, like prime95, just yet. New to oc-ing and some of the setttings from bios (and this mb has quite a few) don't really have a detailed description of what they do (and the manual lists the same thing that bios does
).
