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 value gets a
higher voltage and better overclocking performance, but increases 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 specification.
