▶CPU Vdroop Offset Control [Auto]

Sets a percentage of offset voltage for CPU vdroop. If set to "Auto", BIOS will configure this setting automatically. [Options: Auto, +12.5%, +25%, +37.5%, +50%, +62.5%, +75%, +87.5%, +100%]

▶CPU Over Voltage Protection [Auto]

Sets the voltage limit for CPU over-voltage protection. If set to "Auto", BIOS will configure this setting automatically. Higher voltage provides less protection and may damage the system.

▶CPU Under Voltage Protection [Auto]

Sets the voltage limit for CPU under-voltage protection. If set to "Auto", BIOS will configure this setting automatically. Higher voltage provides less protection and may damage the system.

▶CPU Over Current Protection [Auto]

Sets the current limit for CPU over-current protection. If set to "Auto", BIOS will configure this setting automatically. Higher percentage provides less protection and may damage the system.

▶CPU Switching Frequency [Auto]

Sets the PWM working speed to stabilize CPU Core voltage and minimize ripple range. Increasing the PWM working speed will cause higher temperature of MOSFET. So please make sure a cooling solution is well-prepared for MOSFET before you increase the value. If set to "Auto", BIOS will configure this setting automatically.

▶CPU VRM Over Temperature Protection [Enabled]

Enables or disables the CPU VRM over-temperature protection.

[Enabled]	Sets the temperature limit on CPU VRM for over-temperature
	protection. The CPU frequency may be throttled when CPU VRM
	over the specified temperature.
[Disabled]	Disables this function.

▶CPU Power Duty Control

Selects the method of VRM control for component's phase. [Thermal Balance] Control the VRM with thermal balance mode. [Current Balance] Control the VRM with current balance mode.

▶SVID Communication [Auto]

Enables or disables SVID (Serial Voltage Identification) support.

[Auto]	This setting will be configured automatically by BIOS.
[Enabled]	PWM phase will be changed dynamically according to the CPU SVID
	(Serial Voltage Identification).
[Disabled]	Disables SVID (Serial Voltage Identification) support.

▶VCCIN Voltage [Auto]

Sets the CPU input voltage. The CPU input voltage is the CPU power source that is shared with components of the CPU.

▶Current VCCIN Voltage

Shows current CPU VCCIN voltage. Read-only.
