3. CPU Bus Frequency Selection (U12–Switches 7, 8, 9, 10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock).
The BUS Clock multiplied by the BUS Multiple equals the CPU’s Internal frequency
(the advertised CPU speed).
NOTE: In JumperFree mode, all dip switches must be set to OFF.

NOTE: Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not required for Pentium III/II
processors because they send signals directly to the onboard power regulator.
WARNING! Frequencies above 133MHz exceed the specifications for the on-
board chipset and are not guaranteed to be stable.
