Function no. Function description
4 iGPU Load-line Calibration
Load-line is defined by Intel VRM specifications, and affects the iGPU
voltage. The iGPU working voltage decreases proportionally to integrated
graphics loading. A higher value can get a higher iGPU voltage, and a
good performance, but decreases the CPU and VRM thermal conditions.
5 iGPU Current Capability
A higher value brings 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 Thermal Control
A higher temperature brings a wider CPU power thermal range, and
extends the overclocking tolerance to enlarge overclocking potential.
8 CPU Power Response Control
The DIGI+ VRM controller provides a faster and precise power response
rate for CPU. Apply a higher value for an extreme overclocking.
9 CPU Power Duty Control
CPU Power Duty Control adjusts the current of every VRM phase and the
thermal of every phase component.
