2-15

Allows you to set the APU (Accelerated Processor Unit) 1.2V voltage. The values range from 

1.2000V to 1.8000V with a 0.01V interval.

Allows you to set the VDDA voltage. The values range from 2.5000V to 2.8000V with a 0.1V 

interval.

• 

The values of the CPU Offset Voltage, VDDNB Offset Voltage, DRAM Voltage, 

SB 1.1V Voltage, 1.1VSB Voltage, APU1.2V Voltage, and VDDA Voltage items are 

labeled in different color, indicating the risk levels of high voltage settings.

• 

The system may need better cooling system to work stably under high voltage 

settings.

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: 0% (Regular), 20% (Medium), 60% (High) and 100% 

(Extreme). 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%]
