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 Currrent Capability [Auto] 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: [Auto] [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. Chapter 3 3-10 Chapter 3: BIOS setup

CPU Load-Line Calibration [Auto]
Load-line is defined by AMD 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).
