How do I turn on AMD Cool’n’Quiet™ technology on my Windows Vista machine?
AMD Cool’n’Quiet™ technology is already on in Windows Vista machines, thanks to built-in power management features that do not require additional drivers. To change the power plan, select Control Panel -> Power. The default Windows Vista power profiles that turn on the Cool’n’Quiet and PowerNow! technology features of AMD processors are Balanced and Power Saver.
