The sub-items in this menu display the status of the installed VGA cards and memory. The fields show N/A if there are no devices installed on the slots.

DIGI+ Power Control

CPU Load-Line Calibration [Auto]

Load-line is defined by AMD VRM spec 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 Currrent Capability [Auto]

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: [Auto] [100%] [110%] [120%] [130%]

DO NOT remove the thermal module while changing the DIGI+ Power Control related parrameters . The thermal conditions should be monitored.

Some of the following items are adjusted by typing the desired values using the numeric keypad and press the <Enter> key. You can also use the <+> and <-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard and press the <Enter> key.

CPU Power Phase Control [Standard]

Phase number is the number of woorking 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 Power Switching Frequency [Auto]

Switching frequency will affects the VRM transient response and component thermal. Higher frequency gets quicker transient response.

Configuration options: [Auto] [Manual]

VRM Fixed Frequency Mode

This item appears only when you set the CPU Power Switching Frequency to [Manual]. It allows you to set a fixed frequency range for the VRM. The values range from 300KHz to 550KHz with a 10KHz interval.
