Enabling AMD PowerNow!™ Technology

AMD PowerNow! technology controls your system’s processor performance automatically, dynamically adjusting the operating frequency and voltage according to the task at hand. When an application does not require full performance, significant amounts of power can be saved. Performance is designed to still be responsive, with maximum processor performance being delivered when required, and automatic power savings when possible.

NOTE: AMD PowerNow! support is dependent on the operating system and version used on your system. Disable AMD PowerNow! if your operating system does not fully support this feature. See your operating system user guide for more information.

To disable the AMD PowerNow! feature, run the System Setup Program and disable the Demand-Based Power Management option on the CPU Information screen.
