CPU Power Management

The sub-items in this menu allow you to set the CPU ratio and features.

CPU Ratio [Auto]

Allows you to manually adjust the maximum non-turbo CPU ratio. Use <+> and <-> keys to

adjust the value. The valid value ranges vary according to your CPU model.

Enhanced Intel SpeedStep Technology [Enabled]

Allows you to enable or disable the Enhanced Intel

SpeedStep Technology (EIST).

[Disabled] Disables this function.

[Enabled] The operating system dynamically adjusts the processor voltage and

core frequency which may result in decreased average consumption and

decreased average heat production.

Turbo Mode [Enabled]

Allows you to enable your core processor’s speed to run faster than the marked

frequency in a specic condition. Conguration options: [Disabled] [Enabled]

The rst three items below appear only when you set the Turbo Mode to [Enabled].

Long Duration Power Limit [Auto]

Allows you to limit the turbo ratio’s long duration power.

Use the <+> and <-> keys to adjust the value.

Long Duration Maintained [Auto]

Allows you to maintain the turbo ratio’s long duration power.

Use the <+> and <-> keys to adjust the value.

Short Duration Power Limit [Auto]

Allows you to limit the turbo ratio’s long duration power.

Use the <+> and <-> keys to adjust the value.

Primary Plane Current Limit [Auto]

Maximum instantaneous current allowed at any given time for CPU cores

Use <+> and <-> key to adjust the value at 0.125A increment. .

Secondary Plane Current Limit [Auto]

Maximum instantaneous current allowed at any given time for Internal Graphics cores.

Use <+> and <-> key to adjust the value at 0.125A increment.

DIGI+ VRM

CPU Load-Line Calibration [Auto]

Load-line is dened by Intel VRM spec and affects CPU voltage. The CPU working voltage

will decrease proportionally to CPU loading. Higher value gets a higher voltage and better

overclocking performance, but increases the CPU and VRM thermal. This item allows you to

adjust the voltage range from the following percentages to boost the system performance:

0% (Regular), 25% (Medium), 50% (High), 75% (Ultra High) and 100% (Extreme).

Conguration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme]

The actual performance boost may vary depending on your CPU specication.
