XP reporting cpu clock at 3.6ghz, when it's only at 3.2...?

[Rodknock]

I've been overclocking the Q6600 today and have settled on a conservative 400x8 setup, which should be giving me 3.2ghz.

Coretemp and several other utilities are correctly showing 3.2ghz.

Windows, however, seems to think it's running at 3.6ghz. When I ran 400x9, which actually SHOULD be 3.6ghz, it reported the clock as 4.0ghz.

I haven't come across this problem before, anyone have any pointers?

What version of Windows?
Where in Windows?

Windows detects the CPU's default multiplier, and multiplies by your current FSB speed, even if you've lowered it in the BIOS for under/overclocking. This should always be 9 on your system.

This part shouldn't happen, though. No idea there.

EXACTLY WHAT I WAS THINKING...

r u sure 4.0ghz is what u saw when u were running 400x9? that shouldn't be happening..

wait.. is the default multiplier on the Q9300 = 7.5?
if yes, then everything above is just weird..

if u right click on my computer, the reported speed u should see there is your BIOS SET FSB x DEFAULT MULTIPLER.

what OS are u using?

Oops, forgot to mention the exact OS.

XP w/ sp3 rc2


"The multiplier should always be 9 on your system"

There are several overclocking setups for this cpu/board combo, many of them have a lowered multiplier to benefit from the higher FSB speed.
