Using the System Setup Program
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. Do not
enable AMD PowerNow! if your operating system does not fully support this feature. See your operating system
user guide for more information.
To enable the AMD PowerNow! feature, run the System Setup Program and enable the Demand-Based
Power Management option on the CPU Information screen.
Additionally, for Microsoft
®
Windows
®
operating systems, you will need to install the AMD PowerNow!
driver to enable this feature. The driver is available on the Dell OpenManage Service and Diagnostic CD
provided with your system, and at support.dell.com.
