CPU Offset Mode Sign [+]

This item appears only when you set the CPU Voltage item to [Offset Mode].

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

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

Some of the following items are adjusted by typing the desired values using the numeric

keypad and press the <Enter> key. You can also use the <+> and <-> keys to adjust the

value. To restore the default setting, type [auto] using the keyboard and press the <Enter>

key.

CPU Offset Voltage [Auto]

This item appears only when you set the CPU Voltage item to [Offset Mode] and allows

you to set the Offset voltage. The values range from 0.005V to 0.635V with a 0.005V

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.

iGPU Voltage [Offset Mode]

[Manual Mode] Allows you to set a xed iGPU voltage.

[Offset Mode] Allows you to set the iGPU Offset voltage.

iGPU Offset Voltage [Auto]

This item appears only when you set the iGPU Voltage item to [Offset Mode] and allows you

to set the Offset voltage. The values range from 0.005 to 0.635V with a 0.005V interval.

DRAM Voltage [Auto]

Allows you to set the DRAM voltage. The values range from 1.185V to 2.135V with a 0.005V

interval.

According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage

the CPU permanently. We recommend you install the DIMMs with the voltage requirement

below 1.65V.

• The values of the CPU Manual Voltage, CPU Offset Voltage, iGPU Manual Voltage,

iGPU Offset Voltage, DRAM Voltage, and PCH Voltage items are labeled in different

color, indicating the risk levels of high voltage settings.

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

settings.
