Cool'n'Quiet should be Enabled in system BIOS In Windows XP and 2000: Operating Systems " Minimal Power Management " profile must be active in " Power Schemes ". A PPM driver was also released by AMD that facilitates this.
The adaptation of PowerNow! for AMD's desktop CPUs is called Cool'n'Quiet. Newer Opterons also use an adaptation of PowerNow! called Optimized Power Management. AMD has supplied and supported drivers for its PowerNow! technology that work on Windows 98, ME, NT, and 2000. [2] [3]
AMD's Cool'n'Quiet technology is used on its desktop and server processor lines. The aim of Cool'n'Quiet is not to save battery life, as it is not used in AMD's mobile processor line, but instead with the purpose of producing less heat, which in turn allows the system fan to spin down to slower speeds, resulting in cooler and quieter operation ...
P0 is always the highest-performance state, with P1 to Pn being successively lower-performance states. The total number of states is device or processor dependent, but can be no greater than 16. [41] P-states have become known as SpeedStep in Intel processors, as PowerNow! or Cool'n'Quiet in AMD processors, and as PowerSaver in VIA processors.
Underclocking can be done manually in the BIOS or with Windows applications, or dynamically using features such as Intel's SpeedStep or AMD's Cool'n'Quiet. In Windows 7 and 10, underclocking can be set within the "advanced" settings of a power management plan. [6] [7]
Athlon 64 also features CPU speed throttling technology branded Cool'n'Quiet, a feature similar to Intel's SpeedStep that can throttle the processor's clock speed back to facilitate lower power use and heat output. [52]
