How to enable AMD's Cool'n'Quiet feature in Vista
Posted: Mon Feb 12, 2007 12:37 pm
I'm not sure how many people are having problems with AMD's Cool'n'Quiet in Vista, but to those that are these Dos and Don'ts should really help you out.
To enable AMD’s Cool’n’Quiet feature within Windows Vista:
“DOs:”
· C’n’Q must be “enabled” in the motherboard’s BIOS (Note that most BIOS settings disable it by default)
· The power management scheme/setting must be "balanced" or "power-saver" in the Vista OS control panel
· The motherboard’s BIOS must recognize the CPU that is installed (BIOS status screen will properly display CPU model number upon boot-up)
“DON’Ts:”
· Do NOT Select “Performance” as Vista’s power management scheme/setting as it will disable C’n’Q functionality
· Do NOT manually set the CPU frequency or multiplier in the BIOS. Doing so will lock the processor speed and disable C’n’Q functionality
· Having an old BIOS that does not properly recognize the CPU may disable C’n’Q functionality (ßflash your BIOS to latest version)
· There is NO need to install a separate AMD CPU driver… Vista has the AMD CPU driver built-in already!
You can make verify C’n’Q is working with a utility tool such as “CPU-Z” or one from AMD like the Clock or the Dashboard:
