and press <Enter>.

Changing the values in this menu may cause the system to become unstable! If this

happens, revert to the default settings.

2.5.7 APU Voltage [Offset Mode]

[Offset Mode] To offset the voltage by a positive or negative value.

CPU Offset Mode Sign [+]

[+] To offset the voltage by a positive value.

[–] To offset the voltage by a negative value.

CPU Offset Voltage [Auto]

Allows you to set the CPU Offset voltage. The values range from 0.00625V to

0.40000V with a 0.00625V interval.

Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage

may damage the CPU permanently, and setting a low voltage may make the system

unstable.

VDDNB Offset Mode Sign [+]

[+] To offset the voltage by a positive value.

[–] To offset the voltage by a negative value.

VDDNB Offset Voltage [Auto]

Allows you to set the Southbridge 1.1V voltage. The values range from 1.10V to 1.22V with a

0.04V interval.

• The values of the CPU Offset Voltage, VDDNB Offset Voltage, DRAM Voltage, and

SB 1.1V Voltage items are labeled in different colors, indicating the risk levels of high

voltage settings.

• The system may need better cooling system to work stably under high voltage

settings.
