How to Disable AMD's Cool'n'Quiet

By Nathan McGinty

Chipmaker AMD's Cool N'Quiet technology senses when the CPU isn't being used by the system and decreases voltage to the chip, thereby decreasing energy usage. This technology, however, may not be appropriate in a business situation, such as a server that is constantly in use. In that case, you may want to disable Cool N'Quiet. The way to do is is by entering into your computer's Basic Input Output System (BIOS) before the system boot.

Shut down and reboot your AMD system.

Hold down the "F1" key when the BIOS screen first appears.

Select the "Advanced" tab in the BIOS by pressing the arrow keys until the "Advanced" tab is highlighted. Press "Enter.

Scroll down the menu choices using the up and down arrow keys until "CPU Options" is highlighted. Press "Enter."

Highlight the "Cool N'Quiet" menu item and press "Enter."

Highlight the menu item that says "Enabled." Hit the "+" key to change this to Disabled.

Hit "Esc" until you are back at the main menu. Press "F10" to save your choices and exit.
