1) CPU External Frequency Selection (DIP_SW Switches 6-10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
the PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock).
The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal fre-
quency (the advertised CPU speed).

NOTE: 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 VID signals directly to the onboard power
controller.
