▶ DRAM CH_A/B, CH_C/D Phase Control [Auto]
Controls PWM phase proportionally according 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.
[Optimized] Sets the optimum power phase profile.
[Disabled] Disables the PWM power phase switching feature.
▶ DRAM CH_A/B, CH_C/D 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 CH_A/B, CH_C/D 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 CH_A/B, CH_C/D 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.
▶ DRAM CH_A/B, CH_C/D 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 CH_A/B, CH_C/D 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.
▶ 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.
