▶ 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 protection. [Disabled] Disables this function. ▶ Digital Compensation Level [Auto] Sets the current compensation level for CPU PWM when the MOS phases are changed. If set to "Auto", BIOS will configure this setting automatically. Higher compensation level provides more overclocking ability. ▶ Imon Overwrite [Auto] Sets the Imon current for CPU. [Auto] This setting will be configured automatically by BIOS. [Quarter] Sets the Imon current into quarter. [Half] Sets the Imon current into half. [Disabled] Sets the default values for Imon current. ▶ Transient Boost [Disabled] Enables or disables the transient boost. [Enabled] Enables this function may lead into a stable system under heavy system loading. [Disabled] Disables this function. ▶ 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. ▶ Current VCCIN Voltage Shows current CPU VCCIN voltage. Read-only. ▶ CPU Core Voltage Mode/ CPU Ring Voltage Mode/ CPU GT Voltage Mode [Auto] Selects the control modes for these voltages. [Auto] This setting will be configured automatically by BIOS. [Adaptive Mode] Sets adaptive voltages automatically for optimizing the system performance. [Override Mode] Allows you to set these voltages manually. Chapter 3 3-21 BIOS Setup

BIOS Setup
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
protection.
[Disabled]
Disables this function.
Digital Compensation Level [Auto]
Sets the current compensation level for CPU PWM when the MOS phases are
changed.
If set to "Auto",
BIOS will configure this setting automatically. Higher
compensation level provides more overclocking ability.
Imon Overwrite [Auto]
Sets the Imon current for CPU.
[Auto]
This setting will be configured automatically by BIOS.
[Quarter]
Sets the Imon current into quarter.
[Half]
Sets the Imon current into half.
[Disabled]
