Chapter 2: BIOS information 2-17
2.4.8 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.35V to 2.30V with a 0.01V
interval.
2.4.9 SB 1.1V Voltage [Auto]
Allows you to set the Southbridge 1.1V voltage. The values range from 1.1V to 1.4V with a
0.01V interval.
2.4.10 1.1Vsb Voltage [Auto]
Allows you to set the 1.1Vsb voltage. The values range from 1.1000V to 1.2000V with a 0.1V
interval.
2.4.11 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.
2.4.12 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.
2.4.13 DIGI + VRM
CPU Load Line Calibration [Auto]
CPU 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), 25% (Medium), 50% (High),
75% (Ultra High) and 100% (Extreme). Configuration options: [Auto] [Regular] [Medium]
[High] [Ultra High] [Extreme]
The actual performance boost may vary depending on your CPU specifiation.
CPU/NB Load Line Calibration [Auto]
Allows you to select the CPU/NB Load-Line Calibration mode. Configuration 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.
Configuration options: [100%] [110%] [120%] [130%] [140%]
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.
Configuration options: [100%] [110%] [120%] [130%]
CPU Power Phase Control [Standard]
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.
CPU Voltage Frequency [Auto]
Switching frequency will affect the VRM transient response and component thermal. Setting a
higher frequency gets faster transient response.
[Auto] Allows you to enable or disable the Spread Spectrum item.
[Manual] Allows you to manually set the frequency with a 10k Hz interval.
VRM Spread Spectrum [Disabled]
This item appears only when you set the CPU Voltage Frequency item to [Auto] and allows
you to enable the spread spectrum to enhance system stability.
VRM Fixed Frequency Mode [xxx]
This item appears only when you set the CPU Voltage Frequency item to [Manual] and allows
you to set a fixed VRM frequency. Use the <+> and <-> keys to adjust the value. The values
range from 200k Hz to 400k Hz with a 10k Hz interval.
CPU Power Duty Control [T.Probe]
[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.
2.4.14 APU Spread Spectrum [Auto]
[Auto] Automatic configuration.
[Disabled] Enhances the PCIE overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
