< Voltage Setting >
▶ DigitALL Power
Press <Enter> to enter the sub-menu. Controls the digital powers related to CPU
PWM.
▶ VR 12VIN OCP Expander [Auto]
Expands the limitation of VR Over Current Protection with 12V input voltage. The
higher expanding value indicates less protection. Therefore, please adjust the
current carefully if needed, or it may damage the CPU/ VR MOS. If set to "Auto",
BIOS will configure this setting automatically.
▶ CPU Phase Control [Auto]
Controls PWM phase proportionally to the CPU loading. If set to "Auto", BIOS will
optimize the CPU PWM phase automatically.
[Auto] This setting will be configured automatically by BIOS.
[Normal] Sets the normal power phase profile for CPU, it could provide a
stable system proformance and effective power-saving capability.
[Optimized] Sets the optimum power phase profile for CPU, it could provide the
system with an optimum power-saving capability.
[Disabled] Disables the PWM power phase switching feature.
▶ CPU Vdroop Offset Control [Auto]
Sets a percentage of offset voltage for CPU vdroop. If set to "Auto", BIOS will
configure this setting automatically.
▶ 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 voltage 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.
