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.
DRAM Phase Control [Auto]
Controls PWM phase proportionally to the DRAM loading. If set to "Auto", BIOS
will optimize the DRAM PWM phase automatically.
[Auto] This setting will be configured automatically by BIOS.
[Disabled] Disables the PWM power phase switching feature.
DRAM Switching Frequency [Auto]
Sets the PWM working speed to stabilize DRAM voltage and minimize ripple range.
If set to "Auto", BIOS will configure this setting automatically.
