Chapter 4: Software support

DIGI+ PowerControl allows you to adjust VRM voltage and frequency modulation to enhance 

reliability and stability. It also provides the highest power efficiency, generating less heat to 

longer component lifespan and minimize power loss.

After installing AI Suite II from the motherboard support DVD, launch DIGI+ Power Control 

by clicking Tool > DIGI+ Power Control on the AI Suite II main menu bar.

Select CPU Power or DRAM Power to adjust the power control settings.

1

CPU Load-line Calibration 

It allows you to adjust the voltage settings and control the system temperature. 

Higher load-line calibration could get higher voltage and good overclocking 

performance but increases the CPU and VRM thermal. 

2

CPU Current Capability 

CPU Current Capability provides wider total power range for overclocking. A higher 

value setting gets higher VRM power consumption delivery.

3

CPU Voltage Frequency 

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

Higher frequency gets quicker transient response.

4

VCCSA Load-line Calibration 

The behavior of the DRAM Controller is decided by the VCCSA Load-line. Set to a 

higher value for system performance, or to a lower value for better thermal solution. 

5

VCCSA Current Capability 

A higher value brings wider total DRAM Controller power range and extends the 

overclocking frequency range simultaneously.

6

CPU Power Phase Control 

Increase phase number under heavy system loading to get more transient and 

better thermal performance. Reduce phase number under light system loading to 

increase VRM efficiency.

7

CPU Power Duty Control 

CPU Power Duty Control adjusts the current of every VRM phase and the thermal of 

every phase component.
