CPU VCore [1.750V] (for Willamette), [1.500V] (for Northwood)

When the CPU VCore Setting parameter above is set to [Manual], the CPU VCore item allows you to select a specific CPU core voltage. This field is not accessible when the CPU VCore Setting is set to [Auto].

Depending on the OVER_VOLT jumper setting (see page 2-19 for the jumper location and settings), the CPU core voltage options vary for both Willamette and Northwood processors. See the following table.

Refer to the CPU documentation before setting this field. A very high core voltage may severely damage the CPU!
