Chapter 3
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 specific condition. Configuration options: [Disabled] [Enabled]
The first 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 defined 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).
Configuration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme]
The actual performance boost may vary depending on your CPU specification.
