Chapter 3: BIOS setup

Chapter 3

The following items appear only when you set the CPU Voltage Frequency to [Auto].

VRM Spread Spectrum [Disabled]

Enable the VRM Spread Spectrum to enhance system stability.

Conguration options: [Disabled] [Enabled]

Active Frequency Mode [Disabled]

Set this item to [Enabled] to help enhance the power saving condition while

switching frequencies. While a higher frequency makes the VRM transient

response much faster, switching frequencies affect the VRM thermal

components.

Conguration options: [Disabled] [Enabled]

CPU Power Phase Control [Auto]

Allows you to set the power phase control of the CPU.

Conguration options: [Auto] [Standard] [Optimized] [Extreme] [Manual Adjustment]

DO NOT remove the thermal module when setting this item to [Extreme] and [Manual

Adjustment]. The thermal conditions should be monitored.

The following item appears only when you set the CPU Power Phase Control to [Manual

Adjustment].

Manual Adjustment [Fast]

Allows you to set a faster phase response for the CPU to increase system

performance or to slower phase response to decrease DRAM power

efciency.

Conguration options: [Ultra Fast] [Fast] [Medium] [Regular]

CPU Power Duty Control [T.Probe]

DIGI + VRM Duty Control adjusts the current of every VRM phase and the thermal

conditions of every phase component.

[T. Probe] Select to maintain the VRM thermal balance.

[Extreme] Select to maintain the current VRM balance.

DO NOT remove the thermal module. The thermal conditions should be monitored.

CPU Current Capability [Auto]

DIGI+ VRM CPU Current Capability provides wider total power range for overclocking.

A higher value setting gets higher VRM power consumption delivery and extends the

overclocking frequency range simultaneously.

Conguration options: [Auto] [100%] [110%] [120%] [130%] [140%]

Choose a higher value when overclocking, or under a high CPU loading for extra power

support.
