DIGI+ VRM CPU Load-line Calibration [Auto] Load-line is defined by Intel VRM spec and affects CPU voltage. The CPU working voltage will decrease proportionally to CPU loading. Higher Load-line calibration would get higher voltage and better overclocking performance, but increase the CPU and VRM thermal. This item allows you to adjust the voltage range from the following percentages to boost the system performance: 0% (Regular), 25% (Medium), 50% (High), 75% (Ultra High) and 100% (Extreme). Configuration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme] The actual performance boost may vary depending on your CPU specifiation. CPU/NB Load Line Calibration [Auto] Allows you to select the CPU/NB Load-Line mode. Configuration options: [Auto] [Regular] [High] [Extreme] CPU Current Capability [100%] This item provides wider total power range for overclocking. A higher value brings a wider total power range and extends the overclocking frequency range simultaneously. Configuration options: [100%] [110%] [120%] [130%] [140%] Do not remove the thermal module while changing the DIGI+ VRM related parrameters . The thermal conditions should be monitored. Some of the following items are adjusted by typing the desired values using the numeric keypad and press the key. You can also use the and keys to adjust the value. To restore the default setting, type [auto] using the keyboard and press the key. CPU/NB Current Capability [100%] This item provides wider total power range for overclocking. A higher value brings a wider total power range and extends the overclocking frequency range simultaneously. Configuration options: [100%] [110%] [120%] [130%] CPU Power Phase Control [Standard] Phase number is the number of woorking VRM phase. Increasing phase number under heavy system loading to get more transient and better thermal performance. Reducing phase number under light system loading to increase VRM efficiency [Standard] [Optimized] [Extreme] [Manual Adjustment] Proceeds phase control depending on the CPU loading. Loads the ASUS optimized phase tuning profile. Proceeds the full phase mode. Allows manual adjustment. CPU Voltage Frequency [Auto] Allows you to select the CPU Voltage Frequency.
