The following item appears only when CPU VRM Switching Frequency is set to [Auto].
VRM Spread Spectrum
Allows you to reduce the magnitude of peak noise from the VRM. Enable this item to
reduce peak noise. Disable this settings when overclocking.
Configuration options: [Auto] [Disabled] [Enabled]
CPU Power Duty Control
CPU power duty control adjusts the duty cycle of each VRM phase based upon
current and/or temperature.
[Auto] Automatically selects the power duty control.
[T. Probe] Sets the buck controller to balance VRM FET temperatures
[Extreme] Select to set the VRM current balance mode.
DO NOT remove the thermal module when setting this item to [Extreme]. The thermal
conditions should be monitored.
CPU Power Phase Control
Allows you to set the power phase control of the CPU.
Configuration options: [Auto] [Standard] [Optimized] [Extreme]
DO NOT remove the thermal module when setting this item to [Extreme]. The thermal
conditions should be monitored.
CPU Power Thermal Control
Allows you to set the VRM thermal cut-off trip point. 125 Celsius is default and
recommended for all overclocking and normal use. Can be set to a lower value if a
lower thermal cut-off point is preferred. Use the <+> or <-> to adjust the value.
DO NOT remove the VRM heatsink.
The following items appear only when using the onboard graphics.
CPU Graphics Load-line Calibration
The load-line is defined by the Intel VRM specification and affects the CPU Graphics
power voltage. The CPU Graphics working voltage will decrease proportionally
depending on the CPU Graphics loading. Higher levels of the load-line calibration
can get a higher voltage and a better overclocking performance but increase the CPU
Graphics and VRM thermal production. Select from level 1 to 8 to adjust the CPU
Graphics power voltage from 100% to 0%.
Configuration options [Auto] [Level 1] [Level 2] [Level 3] [Level 4:Recommended for
OC] [Level 5] [Level 6] [Level 7] [Level 8]
Boosted performance may vary depending on the CPU Graphics specification. DO NOT
remove the thermal module.
