Limit processor frequency in windows

Most of the new processors support a range of frequencies (like: 600 - 1700 MHz).

Through the PWR managment schemes i can change the processor to be adaptive (min - max), constant (max), most battery (min).

Does windows give an interface to define a certain range of frequencies or to run the processor on a given frequency If not is there any way to do it

Thanks alot,

AFAIK, Windows doesn't allow controlling CPU at the level of specifying clock speeds. You can only configure how the CPU should adjust the frequency by the appropriate power scheme.

This is not really an architecture question.. but what the heck

As Siva said windows can only control CPU modes (as defined in the ACPI standard - you can read more about it here :http://www.microsoft.com/whdc/system/pnppwr/powermgmt/ProcPerfCtrl.mspx

You can change CPU multipliers and FSB speeds (Overclock or UnderClock) by working with the BIOS /CPU see for example ttp://www.panopsys.com/Developers.html
