I finally upgraded my OS from XP to vista (enterprise version), but after upgrade OS, I am stuck at the lower CPU multiplier of intel Core 2 Duo e6300 (x6 instead of x7).

The motherboard I am using is gigabyte 965p-ds3, with firmware f10, I set the multiplier to x7 in bios, and I can see from the POST message that the x7 is effective, but as soon as I enter vista, I only see x6 (checked from cpu-z, also that is what the vista reported in control panel).

so then I installed gigabyte easytune, what is interesting here is now when I set the new FSB, the multiplier setting says x7, and the calculation is done using x7, but as soon as I hit "Go" button, the actual effective CPU clock is using x6..

where else I can check to fix this weird problem? right now I have to set the FSB to very high number, I am afraid this will generate too much heat from the MB chips... can anyone throw some ideas, thanks in advance!

EIST enabled?
if so it's just the CPU scaling back when not needed - put it under load & it should change up to 7x
