CPU CONFIGURATION
INTEL SPEEDSTEP TECHNOLOGY
Intel SpeedStep technology is Intel’s new power saving technology. Processors can switch between multiple
frequencies and voltage points to enable power saving. The default value is [Enabled]. Configuration options:
[Enabled] and [Disabled]. If you install Windows
®
8 / 8.1 and want to enable this function, please set this item
to [Enabled]. This item will be hidden if the current CPU does not support Intel SpeedStep technology.
Please note that enabling this function may reduce CPU voltage and lead
to system stability or compatibility issues with some power supplies.
Please set this item to [Disabled] if above issues occur

software to execute codes. This option will be hidden if the current CPU does not support No-Execute Memory
Protection.
