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.

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 frequenciesa affect the VRM thermal components.

CPU Power Phase Control [Auto]
Allows you to set the power phase control of the CPU.

DO NOT remove the thermal module when setting this item to [Extreme]. The thermal
conditions should be monitored.
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.

Choose a higher value when overclocking, or under a high CPU loading for extra power
support.
CPU Power Thermal Control [130]
A higher temperature brings a wider CPU power thermal range and extends the overclocking
tolerance to enlarge the O.C. potential. Use the <+> or <-> keys to adjust the value. The
values depend on the CPU installed.
DO NOT remove the thermal module. The thermal conditions should be monitored.
