3-24 BIOS Setup 3-25 BIOS Setup
▶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.
▶DRAM VRM Over Temperature Protection [Auto]
Sets the temperature limit on DRAM VRM for over-temperature protection. The
DRAM frequency may be throttled when DRAM VRM over the specified temperature.
If set to "Auto", BIOS will configure this settings.
▶DRAM Power Duty Control [Thermal Balance]
Selects the method of VRM control for DRAM phase.
[Thermal Balance] Control the VRM with thermal balance mode.
[Current Balance] Control the VRM with current balance mode.
▶PCH Vdroop Offset Control [Auto]
Sets a percentage of offset voltage for PCH vdroop. If set to "Auto", BIOS will
configure this setting automatically.
▶PCH Over Voltage Protection [Auto]
Sets the voltage limit for PCH over-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and
may damage the system.
▶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.
