With just a small increase in FSB from 443 to 445 the pc will restart after a few seconds of small FFT's and Im trying all sorts of different bios options to fix it without success. Load temps are in the low-mid 60's before it reboots.

Any ideas? I noticed you ran 30mins small FFT at 4005.

Do you think it is my motherboard limit ? Not sure why it doesn't just fail prime rather than rebooting.

I thought it may be FSB wall but I can get it upto 515 with x8 multi.
It is not limited by MB, it will reboot rather than giving you a error message when CPU is unstable, I tested for many Core2duo or Core2quad with many different MBs, having such symptom.
It is one of the best MB for Quad I have ever used, some MBs even can't boot at 460FSB or above with the same quadcore CPU.
