Cool'n'Quiet
Cool’n’Quiet is an attempt by AMD to reduce the core temperature of their processors. This process is very similar to that of PowerNow! in AMD’s current mobile processors.
With Cool’n’Quiet, what happens is the frequency and core voltages will be throttled back or forth depending on the demands of the system itself. Whenever the CPU is not under 100% load, both the nominal core voltage and frequency of the processor will be throttled back, in turn creating less heat. Processor clock speeds should decrease to as low as 800MHz at idle all the way up to maximum frequency, 2.2GHz in this case, at 100% CPU load.
First off, to take advantage of this feature, your motherboard must support it. If your motherboard does support the Cool’n’Quiet feature, then the next step is to download the newest processor driver at AMD.
You can get the latest drivers here.
After this is done, you’ll need to activate this feature in your operating system. This is done by setting your power management scheme to Minimal Power Management.
There is a toolkit provided by AMD that allows you to see if this feature has indeed been enabled on your system. It is available here. This toolkit allows you to see your clock speed, your core voltage as well as other useful information.
