Windows 7 showing wrong CPU speed.

I recently upgraded to Windows 7, and in Xp my overclock showed correctly. As 333X10.5=3500 but even though my bios settings are still the same and all c1e is turned off, windows 7 is showing that i have 266x10.5=2800. cpu-z shows this aswell, including asus utility (every program i've tried has said the same)

Any ideas as to why windows 7 shows this? and is windows 7 really underclocking my system? or is this just windows 7 showing inaccurately?

Don't forget to turn off both C1E halt state and also "speed step", unless the bios settings were messed with that should work. But in most cases and if you aren't overclocking those settings can save power and are very useful.

Make sure you aren't using one of those lame Windows overclock utilities because they will mess with your bios settings big time.

No i'm not using anything like that, but i realised that no matter what i do to the bios, it wont boot unless everything is set to auto. so i'm going to try doing a cmos clear and see, or even try a modded bios. since i'm running out of options. i;ve made another thread here for this.
