I have had to update my Standard P5K bios to 0603 to support the G0 stepping chips but since doing so Im having problems.


When I run prime after about 20 seconds the multiplier will switch from x9 to x6 lowering my clock, its like speedstep in reverse and btw speedstep is disabled in my bios.


For example...

Here is my rig ready to run prime95.




Now, here it is running after a few seconds.




This happens no matter what speed Im running.

Its fine with my E2160 chip it just happens with my Q6600 G0


Any ideas anyone ?
