Function no. 4 5 6 7 8 9 Function description 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. iGPU Current Capability A higher value brings wider total iGPU power range, and extends the overclocking frequency range simultaneously to enhance the iGPU performance. 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. * The system automatically set the default to [Extreme] when using the Intel® iGPU. CPU Power Thermal Control A higher temperature brings a wider CPU power thermal range, and extends the overclocking tolerance to enlarge overclocking potential. 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. CPU Power Duty Control CPU Power Duty Control adjusts the current of every VRM phase and the thermal of every phase component. Chapter 4 4-10 Chapter 4: Software support
