If you have speedstep enabled in the bios then it will slow the cpu down to a multiplier of 6 when it isn't under a heavy load. But when you start a program that puts a load on the cpu it should let the cpu go up to its full multiplier. If your cpu isn't doing that then there is a possibility that the multiplier is set wrong in the bios. You didn't say if this was a laptop or not- my Dell laptop can be set to limit the maximum cpu speed for power conservation. If I change the profile to performance then it will allow the cpu to run at its full speed.
