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 protec-
tion. 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.
▶ 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.
