It has been a while since i played with this board. One thing is to keep active cooling on the Northbridge and the PWM area. I was using this board for a Phenom X6 and found that PWM area ran extremely hot. So make sure to keep it cool in order to start to achieve anything over 265HTT. I also never pushed the processor voltage over 1.55, but I did move the northbridge voltage up a small amount. I also found it better to use a discreet video card over the onboard to keep it cooler as well.Other than that I really don't remember enough of my settings to be to much of a help. Sorry.
