item to a value other than [Auto].

[+]

To offset the voltage by a positive value.

[–]

To offset the voltage by a negative value.

Fixed Voltage [Auto]

This item appears only whne you set the

CPU Voltage Mode

item to [Manual] and allows you

to set a ﬁxed CPU voltage. The values range from 0.85V to 2.10V* with a 0.00625V interval.

•

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

VCore voltage may damage the CPU permanently, and setting a low VCore voltage

may make the system unstable.

•

If the
