9.VCORE over-voltage (3-pin OVER_VOLT)

When set to Normal, this jumper allows CPU Vcore ranges of 1.75V to 1.85V for Pentium 4 Willamette and 1.5V to 1.7V for Northwood.

When set to Over Voltage, Willamette will have a Vcore setting range of +1.75V to +2.1V, and Northwood 1.50V to 1.75V. You may adjust the CPU VCore through the BIOS Setup. See page 4-16 for more information.

Setting to a very high core voltage may cause permanent damage to the CPU! It is recommended that you keep the default setting (Normal).
