Load-line Calibration is defined by AMD VRM specifications and affects CPU voltage. The 

CPU working voltage will decrease proportionally to CPU loading. Higher load-line calibration 

would get higher voltage and better overclocking performance, but increase the CPU and 

VRM thermal. This item allows you to adjust the voltage range from the following percentages 

to boost the system performance. Configuration options: [Auto] [Regular] [Medium] [High] 

[Extreme]

The actual performance boost may vary depending on your CPU specifiation.

Allows you to select the CPU/NB Load-Line Calibration mode. Configuration options: [Auto] 

[Regular] [High] [Extreme]

This item provides wider total power range for overclocking. A higher value brings a 

wider total power range and extends the overclocking frequency range simultaneously. 

Configuration options: [100%] [110%] [120%] [130%]

Phase number is the number of working VRM phase. Increasing phase number under heavy 

system loading to get more transient and better thermal performance. Reducing phase 

number under light system loading to increase VRM efficiency.
[Standard] 

  

Proceeds phase control depending on the CPU loading.

[Optimized] 

  

Loads the ASUS optimized phase tuning profile.

[Extreme] 

  

Proceeds the full phase mode.

[Manual Adjustment]  Allows manual adjustment.

Switching frequency will affect the VRM transient response and component thermal. Setting 

a higher frequency gets faster transient response. Use the <+> and <-> keys to adjust the 

value. The values range from 200k Hz to 350k Hz with a 50k Hz interval.

[T.Probe] 

Maintains the VRM thermal balance.

[Extreme] 

Maintains the VRM current balance.

Do not remove the thermal module while changing the DIGI+VRM related parameters. The 

thermal conditions should be monitored.
