Underclocking, also known as downclocking, is the practice of modifying a synchronous circuit's timing settings to run at a lower clock rate than it was specified to operate at. It may be said to be the computer equivalent to drive a car at a speed below the speed limit. Usually, underclocking is used to reduce a computer's power consumption and heat emission, sometimes also to increase the system's stability and compatibility. Underclocking may be implemented by the factory, but many computers and components are end user underclockable.
