4.3.3 DIGI+ VRM
ASUS DIGI+ VRM allows you to adjust VRM voltage and frequency modulation to enhance
reliability and stability. It also provides the highest power efciency, 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 specication.
• 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 conguration.
Items Function description
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 dened by Intel VRM specications, 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 efciency.
7
CPU Power Duty Control
CPU Power Duty Control adjusts the current of every VRM phase and the thermal of every
phase component.
