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.
