It's likly to be due to SpeedStep, this lowers the CPU speed to save energy, when your computer is idle. It will ramp upto 3.06 or even higher when needed.

you can disable Speedstep or EIST in bios of your mobo, and then the powersaving mode is gone and should run your cpu on the normal speed (+ turbo 1x multiplier)
