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.
Set default to [Extreme] when using the Intel ® iGPU.
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.
