ASUS DIGI+ VRM 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+ VRM by 

clicking Tool > DIGI+ VRM on the AI Suite II main menu bar.

• 

The actual performance boost may vary depending on your CPU specification.

• 

Do not remove the thermal module. The thermal conditions should be monitored.

Refer to the software manual in the support DVD or visit the ASUS website at  

www.asus.com for detailed software configuration.

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

iGPU Load-line Calibration 

Load-line is defined by Intel VRM specifications, and affects the iGPU voltage. The iGPU 

working voltage will decrease proportionally to integrated graphics loading. A higher value can 

get a higher iGPU voltage, and a good performance, but increases the CPU and VRM thermal 

conditions.

5

iGPU Current Capability 

A higher value brings a wider total iGPU power range and extends the overclocking frequency 

range simultaneously to enhance the iGPU performance. 

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.
