The following items from Load-line Calibration to CPU Current Capability are for DIGI+
VRM configurations.
DIGI+VRM
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 specification.
VRM Frequency [Auto]
Switching frequency will affect the VRM transient response and component thermal. Higher
frequency gets quicker transient response. Configuration options: [Auto] [Manual]
VRM Spread Spectrum [Disabled]
Enable Spread Spectrum to enhance system stability. Configuration options: [Auto] [Manual]
VRM Fixed Frequency Mode [XXX]
This item appears only when you set the Frequency item to [Manual] and allows you to
manually set the VRM fixed frequency. The values range from 300kHz to 500kHz with a
10kHz interval.
Phase Control [Standard]
Phase number is the number of working VRM phase. 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.
[Standard]
Phase control based on CPU command.
[Optimized] ASUS optimized phase tuning profile
[Extreme] Full phase mode
[Manual Adjustment] Phase number adjusted by current (A) step
