feature helps conserve battery life by decreasing the CPU's running speed
under certain conditions while still maintaining a high performance. If
this item is enabled, the CPU will automatically change its speed
whenever necessary based on the "Power Scheme" setting in Windows'
Control Panel. If this item is disabled, the CPU will always run in the
lowest speed. The options are Enabled and Disabled. The default setting
is Enabled.
NOTE: This item is available only when the CPU supports the Geyserville feature.
