Can I enable Cool'n'Quiet on my old AMD processor on Windows 7 64-bit? If so, do I need a separate driver (like Windows XP) or I only have to modify some options?

The processor is an AMD Athlon 64 3200+ on an ASUS K8V-MX motherboard.

Enabling Cool’n’Quiet on Windows 7 is the same as it is on Windows Vista…

DOs:

  • C’n’Q must be “enabled” in the motherboard’s BIOS (Note that most BIOS settings disable it by default)
  • For optimal power savings, be sure to also enable C1E and DRAM Power Down in the BIOS
  • The power management scheme/setting must be "balanced" or "power-saver" in the control panel (note that this is the default setting)
  • The motherboard’s BIOS must recognize the CPU that is installed (BIOS status screen will properly display CPU model number upon boot-up)
  • You can verify C’n’Q is working with a utility tool such as “CPU-Z” or “AMD Power Monitor.”

DON'Ts:

  • Do NOT Select “Performance” as Windows 7’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 (flash your BIOS to latest version)
  • There is NO need to install a separate AMD CPU driver… Windows 7 has the AMD CPU driver built-in already!
