3-16 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.
Configuration 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.
Configuration options: [Disabled] [Enabled]
CPU Power Phase Control [Auto]
Allows you to set the power phase control of the CPU.
Configuration 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
efficiency.
Configuration 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.
Configuration options: [Auto] [100%] [110%] [120%] [130%] [140%]
Choose a higher value when overclocking, or under a high CPU loading for extra power
support.
