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.
