3-22 BIOS Setup 3-23 BIOS Setup
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.
[Auto] This setting will be configured automatically by BIOS.
[Enhanced] Extends the limitation of CPU over-current protection.
▶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 [Auto]
Sets the temperature limit on CPU VRM for over-temperature protection. The CPU
frequency may be throttled when CPU VRM over the specified temperature. If set to
"Auto", BIOS will configure this settings.
▶CPU Power Duty Control [Thermal Balance]
Selects the method of VRM control for CPU phase.
[Thermal Balance] Control the VRM with thermal balance mode.
[Current Balance] Control the VRM with current balance mode.
▶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.
[Normal] Sets the normal power phase profile.
[Optimized] Sets the optimum power phase profile.
[Disabled] Disables the PWM power phase switching feature.
▶DRAM Vdroop Offset Control [Auto]
Sets a percentage of offset voltage for DRAM vdroop. If set to "Auto", BIOS will
configure this setting automatically.
▶DRAM Over Voltage Protection [Auto]
Sets the voltage limit for DRAM over-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and
may damage the system.
▶DRAM Under Voltage Protection [Auto]
Sets the voltage limit for DRAM under-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and may
damage the system.
▶DRAM Over Current Protection [Auto]
Sets the current limit for DRAM over-current protection.
[Auto] This setting will be configured automatically by BIOS.
[Enhanced] Extends the limitation of memory over-current protection.
