The following item appears only when the CPU VRM Switching Frequency is set to [Auto].
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]
[Extreme]
DO NOT remove the thermal module. The thermal conditions should be monitored.
CPU Power Phase Control [Auto]
This item allows you to set the power phase control of the CPU.
Configuration options: [Auto] [Standard] [Optimized] [Extreme]
DO NOT remove the thermal module when setting this item to [Extreme]. The thermal
conditions should be monitored.
CPU Graphic Load-line Calibration [Auto]
Load-line is defined by IntelR specification and affects CPU power voltage. The CPU
working voltage decreases proportionally to CPU loading. Higher load-line calibration
could get higher voltage and good overclocking performance, but increases the CPU
and VRM thermal conditions. Select from levels 1 to 7 to adjust the CPU power voltage
from 0% to 100%.
[Auto] [Level 1] - [Level 7]
CPU Graphics Current Capability [Auto]
The GT current capability adjusts the total power range for GT overclocking. A higher
value provides a wider total power range and extends the overclocking frequency
range simultaneously.
Configuration options: [Auto] [100%] [110%] [120%] [130%]
CPU Graphics [Auto]
The switching frequency will affect the GT transient response speed and the
component thermal production. Select the manual mode to configure a higher
frequency to get a quicker transient response speed.
[Auto] [Manual]
The following item appears only when you set the CPU Graphics to [Manual].
2-26
VRM Spread Spectrum [Disabled]
This item allows to enhance the system stability.
Configuration options: [Disabled] [Enabled]
Select to set the VRM thermal balance mode.
Select to set the VRM current balance mode.
Fixed VCCGT Switching Frequency(KHz) [300]
This item allows you to set a higher frequency for a quicker transient
response speed. Use the <+> or <-> to adjust the value. The values range
from 300 KHz to 600 KHz with an interval of 50 KHz.
