▶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.

▶CPU Core Voltage Mode/ CPU Ring Voltage Mode/ CPU GT Voltage Mode [Auto] Selects the control modes for these voltages.

[Auto]	This setting will be configured automatically by BIOS.
[Adaptive Mode]	Sets adaptive voltages automatically for optimizing the system
	performance.
[Override Mode]	Allows you to set these voltages manually.

▶CPU Core Voltage/ CPU Ring Voltage/ CPU GT Voltage [Auto]

Sets these voltages. If set to "Auto", BIOS will set these voltages automatically or you can set it manually.

▶CPU Core Voltage Offset Mode/ CPU Ring Voltage Offset Mode/ CPU GT Voltage Offset Mode/ CPU SA Voltage Offset Mode/ CPU IO Analog Voltage Offset Mode/ CPU IO Digital Voltage Offset Mode [Auto]

Selects the voltage offset modes.

[Auto] This setting will be configured automatically by BIOS.

[+]Allows you to set the positive offset voltage.

[-] Allows you to set the negative offset voltage.

▶CPU Core Voltage Offset/ CPU Ring Voltage Offset/ CPU GT Voltage Offset/ CPU SA Voltage Offset/ CPU IO Analog Voltage Offset/ CPU IO Digital Voltage Offset [Auto]

Set the offset values for these voltages.

▶Current CPU Core Voltage/ Current CPU Ring Voltage/ Current CPU GT Voltage/ Current CPU SA Voltage/ Current CPU IO Digital Voltage

Show the current voltages. Read-only.

▶Internal VR OVP OCP Protection [Auto]

Enables or disables the over-voltage protection and over-current protection for CPU internal VR (Voltage Regulator).

[Auto]	This setting will be configured automatically by BIOS.
[Enabled]	Sets the voltage limit on the CPU internal VR for over-voltage protection
	and over-current protection.
[Disabled]	Disables this function for overclocking.

▶Internal VR Efficiency Management [Auto]

Enables or disables the CPU internal VR efficiency management.

[Auto]	This setting will be configured automatically by BIOS.
[Enabled]	Enables the VR effciency management for power-saving control.
[Disabled]	Disables this function.

▶DRAM Voltage [Auto]

Sets the memory voltage. If set to "Auto", BIOS will set memory voltage automatically or you can set it manually.
