CPU Power Management Configuration

Intel SpeedStep Technology

Intel SpeedStep technology is Intel’s new power saving technology. Pro- cessor can switch between multiple frequency and voltage points to en- able power savings. The default value is [Enabled]. Configuration options: [Enabled] and [Disabled]. If you install Windows® VistaTM / 7 and want to enable this function, please set this item to [Enabled]. This item will be hid- den if the current CPU does not support Intel SpeedStep technology.
