The following nine (9) items are adjusted by typing the desired values using
the numeric keypad and press the 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 key.
CPU Voltage [Auto]
Allows you to select the CPU VCore voltage. The text color in the configuration
field corresponds to the onboard CPU LED color, both of which indicate voltage
condition. When you set the CPU LED Selection item to [Vcore], the onboard
CPU LED displays CPU VCore voltage condition. Refer to page 2-2 for CPU LED
definition. The values range from 0.85000V to 2.50000V with a 0.00625V interval.
The CPU voltage could be set only up to 1.8V when the Extreme OV item is set
to [Disabled].
Refer to the CPU documentation before setting the CPU VCore voltage. Setting
a high voltage may damage the CPU permanently, and setting a low voltage
may make the system unstable.
