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

When enabled, this jumper allows a CPU Vcore setting range of +1.75V to +2.1V for Pentium 4 Willamette processor, and a 1.475V to 1.75V range for Northwood processor through BIOS Setup. When disabled, the allowed Vcore settings are lower.

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