DIGI+ VRM
CPU Load-Line Calibration [Auto]
Load-line is dened by Intel VRM specication 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 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).
Conguration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme]
The actual performance boost may vary depending on your CPU specication.
CPU Voltage Frequency [Auto]
Frequency switching affects the VRM transient response, and the thermal component.
Higher frequency gets quicker transient response. Conguration options: [Auto]
[Manual]
DO NOT remove the thermal module when switching to Manual Mode. The thermal
conditions should be monitored.
VRM Spread Spectrum [Disabled]
This item appears only when you set the Frequency item to [Auto] and allows you to
enable the spread spectrum to enhance system stability.
CPU Power Phase Control [Standard]
Allows you to control the power phase based on the CPU’s demands.
Conguration 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 congure the total power range, and extends the overclocking frequency
range simultaneously. Conguration options: [100%] [110%] [120%] [130%] [140%]
