3-20 BIOS Setup 3-21 BIOS Setup
▶PCH Under Voltage Protection [Auto]
Sets the voltage limit for PCH under-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and
may damage the system.
▶PCH Over Current Protection [Auto]
Sets the current limit for PCH over-current protection.
[Auto] This setting will be configured automatically by BIOS.
[Enhanced] Extends the limitation of PCH over-current protection.
▶PCH Switching Frequency [Auto]
Sets the PWM working speed to stabilize PCH voltage and minimize ripple range.
If set to “Auto”, BIOS will configure this setting automatically.
▶PCH VRM Over Temperature Protection [Auto]
Sets the temperature limit on PCH VRM for over-temperature protection. The PCH
frequency may be throttled when PCH VRM over the specified temperature.If set to
"Auto", BIOS will configure this settings.
▶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.
▶CPU Core/Ring Voltage Mode [Auto]*
Selects the control mode for CPU Core/ Ring voltages.
[Auto] This setting will be configured automatically by BIOS.
[Adaptive Mode] Sets the adaptive voltage automatically for optimizing the system
performance.
[Override Mode] Allows you to set the voltage manually.
[Offset Mode] Allows you to set the offset voltage and select the voltage
offset mode.
[Adaptive + Offset ] Sets the adaptive voltage automatically and allows you to set the
offset voltage.
[Override + Offset ] Allows you to set the voltage and the offset voltage manually.
▶CPU Core Voltage/ CPU Ring Voltage [Auto]
Sets the CPU Core/ Ring voltages. If set to “Auto”, BIOS will set these voltages
automatically or you can set it manually. This item appears when “CPU Core/Ring
Voltage Mode” sets to [Auto]/ [Adaptive Mode]/ [Override Mode].
▶CPU Core/ Ring Voltage Offset Mode [Auto]*
Selects the offset mode for CPU Core/ Ring voltage. This item appears when “CPU
Core/Ring Voltage Mode” sets to [Offset Mode]/ [Adaptive + Offset]/ [Override +
Offset].
[Auto] This setting will be configured automatically by BIOS.
[+] Allows you to offset the voltage by positive value mode.
[-] Allows you to offset the voltage by negative value mode.
