Chapter 2: BIOS information 2-15
2.4.12 APU1.2V Voltage [Auto]
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.
2.4.13 VDDA Voltage [Auto]
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.
2.4.14 DIGI+ VRM
CPU Load Line Calibration [Auto]
Load-line Calibration is dened by AMD VRM specications 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). Conguration options: [Auto] [Regular] [Medium] [High] [Extreme]
The actual performance boost may vary depending on your CPU speciation.
CPU/NB Load Line Calibration [Auto]
Allows you to select the CPU/NB Load-Line Calibration mode. Conguration options: [Auto]
[Regular] [High] [Extreme]
CPU Current Capability [100%]
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.
Conguration options: [100%] [110%] [120%] [130%]
CPU/NB Current Capability [100%]
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.
Conguration options: [100%] [110%] [120%] [130%]
