4) CPU External Frequency Setting (DSW Switches 1–4)

This option tells the clock generator what frequency to send to the CPU, SDRAM,
and the chipset. This allows the selection of the CPU’s External frequency. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s
Internal frequency (the advertised CPU speed).

IMPORTANT:

1. To use this feature, check the JEN jumper settings: see Jumper/

JumperFree™ Mode (JEN) on the previous pages.

Frequencies other than the recommended CPU bus frequencies are

not guaranteed to be stable. Overclocking your processor is not recommended. It
may result in a slower speed and premature wearing of the processor.
