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.
