    "Running a processor at high clock speeds allows for better performance. However, when the same processor is run at a lower frequency (speed), it generates less heat and consumes less power. In many cases, the core voltage can also be reduced, further reducing power consumption and heat generation. This can conserve battery power in notebooks, extend processor life, and reduce noise generated by variable-speed fans. By using SpeedStep, users can select the balance of power conservation and performance that best suits them, or even change the clock speed dynamically as the processor bur"
    When you enable speedstep,then when your CPU will downclock itself in idle mode, and will work on its stock clock at load.And when you disable it,your CPU will always run its stock clock.

    what if your overclocked ? will the cpu work at the overclocked speed when under load if speed step is enabled?
