CPU Load-Line Calibration [Auto]
Load-line is defined by Intel VRM specifications, and affects CPU voltage. The CPU working
voltage will decrease proportionally to CPU loading. Higher value gets a higher voltage, and
a better overclocking performance, but increases the CPU and VRM thermal conditions.
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.
CPU Voltage Frequency [Auto]
Switching frequency affects the VRM transient response, and the component thermal. Setting
a higher frequency gets faster transient response.
[Auto]
Allows you to enable or disable the Spread Spectrum item.
[Manual]
Allows you to manually set the frequency with a 10k Hz interval.
DO NOT remove the thermal module when switching to Manual Mode. The thermal
conditions should be monitored.
CPU Fixed Frequency [xxx]
This item appears only when you set the CPU Voltage Frequency item to [Manual] and allows
you to set a fixed CPU frequency. Use the <+> and <-> keys to adjust the value. The values
range from 200k Hz to 400k Hz with a 10k Hz interval.
CPU Power Phase Control [Standard]
Allows you to control the power phase based on the CPU’s demands. Configuration options:
[Standard] [Optimized] [Extreme] [Manual Adjustment]
DO NOT remove the thermal module when switching to Extreme and Manual Mode. The
thermal conditions should be monitored.
CPU Power Duty Control [T.Probe]
DIGI + VRM Duty control adjusts the current and thermal conditions of every component’s
phase.
[T. Probe]
Select to maintain the VRM thermal balance.
[Extreme]
Select to maintain the current VRM balance.
CPU Current Capability [100%]
Allows you to configure the total power range, and extends the overclocking frequency range
simultaneously. Configuration options: [100%] [110%] [120%] [130%] [140%]
Choose a higher value when overclocking, or under a high CPU loading for extra power
support.
