DRAM DATA REF Voltage on CHA/B/C [Auto]
Allows you to set the DRAM DATA Reference Voltage on Channel A/B/C. The values
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM
overclocking ability.
3.5.23
DRAM CTRL REF Voltage on CHA/B/C [Auto]
Allows you to set the DRAM Control Reference Voltage on Channel A/B/C. The values
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM
overclocking ability.
3.5.24
Duty Control [T.Probe]
[Extreme]
Unleashes the power system to push the limit for extreme overclocking.
[T.Probe]
Manages to achieve the optimum thermal performance for longer
components life.
3.5.25
Phase Control [Extreme]
[Standard]
Uses the standard settings.
[Extreme]
Uses the extreme settings.
Refer to 4.3.2 DIGI+ VRM for details.
3.5.26
Load-Line Calibration [Auto]
[Auto]
BIOS automatically adjusts the voltage.
[Disabled]
Follows the Intel specifications.
[Enabled]
Improves the CPU VDroop directly.
