The following item appears only when you set the VDDCR CPU Switching Frequency to
[Manual] .
Fixed VDDCR CPU Switching Frequency (KHz) [300]
This item allows you to set a higher frequency for a quicker transient response speed.
Use the <+> and <-> keys to adjust the value. The values range from 300KHz to
600KHz with a 50KHz interval.
VRM Spread Spectrum [Off]
Enable this item to reduce the peak noise or disable it when overclocking.
Configuration options: [On] [Off]
VDDCR 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.
VDDCR CPU Power Phase Control [Standard]
This item allows you to set the power phase control of the CPU. Configuration options:
[Standard] [Optimized] [Extreme] [Manual]
The following item appears only when you set the VDDCR CPU Power Phase Control to
[Manual] .
Manual Adjustment [Fast]
This item 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]
VDDCR SOC Load Line Calibration [Auto]
Load-line is defined by AMD VRM specification and affects the GT power voltage. The
GT working voltage will decrease proportionally depending on the GT loading. Higher
levels of the load-line calibration can get a higher voltage and a better overclocking
performance but increases the GT and VRM thermal. Select from level 1 to 8 to adjust
the GT power voltage from 0% to 100%. Configuration options: [Auto] [Level 1] [Level
2] ~ [Level 7] [Level 8]
• The boosted performance may vary depending on the GT specification. Do not
remove the thermal module.
• The configuration levels vary depending on the CPUs installed.
VDDCR SOC Current Capability [100%]
Allows you to configure the total power range, and extends the overclocking frequency
range simultaneously. Configuration options: [100%] [110%] [120%] [130%] [140%]
Choose a higher value when overclocking, or under a high GT loading for extra power
support.
