CPU Core Clock Performance Tuning

CPU core clock is the most important item to adjust for the advanced users when tuning the performance of the system. The CPU Clock speed has a big impact on overall system performance. The following steps explain how to determine the CPU tuning margin.

PLEASE NOTE THAT THE AMD PRODUCT WARRANTY DOES NOT COVER DAMAGES CAUSED BY RUNNING COMPONENTS OUTSIDE OF SPECIFICATION INCLUDING DAMAGES CAUSED BY OVERCLOCKING (EVEN WHEN OVERCLOCKING IS ENABLED WITH THE AMD OVERDRIVE UTILITY).

The key BIOS settings to adjust before proceeding with CPU Performance tuning:

∙Disable AMD Turbo Core Technology (can also be disabled via AMD OverDrive utility)

∙Disable APM (Application Power Management) (disabling the AMD Turbo Core Technology via AMD OverDrive utility will also disable APM)

∙Disable “Cool ‘n’ Quiet” –power saving item from the BIOS menu

∙Disable “C1E” –item from the BIOS menu

∙Disable “CPU Fan Control” –item from the BIOS menu (allows max cooling)

∙Ensure that CPU NB, Memory or HT Link values are running at default stable values
