6.CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3)

This option sets the frequency multiple between the Internal frequency of the CPU and the CPU’s External frequency. These must be set in conjunction with the CPU Bus Frequency.

NOTES: Overclocking your processor is not recommended. It may result in a slower speed. Voltage Regulator Output Selection (VID) is not needed for the Pentium III/ II/Celeron processor because it sends a VID signal directly to the onboard power controller.
