Okay. I managed on overclock to 3.25. Settings as follows.
All standard except.
FSB Clock 1299
cpu voltage .10
FSB voltage 1.3
Systemn runs stable with a 22% increase in speed and a 10C increase in core temps under load compared to stock speed and voltage. (around 45C under heavy load. 35-38C normal load.) I have a pretty heavy duty cooling tower
1195 FSB gave me 3.0 mhz with no voltage increase.
