Chapter 2: Hardware information

2. CPU External Frequency Selection (DSW Switches 6-10)

This option tells the clock generator which frequency to send to the CPU,
SDRAM and AGP clock, and sets the CPU’s External frequency. (The BUS
Clock multiplied by the Frequency Multiple equals the CPU’s Internal
frequency, or, the advertised CPU speed.)

IMPORTANT:

1. To use this feature, JEN must be set to Jumper Mode, [1-2].

(See 1, JumperFree™ Mode.)

Set the CPU AND DRAM frequencies only to the recommended settings.
Frequencies other than the recommended CPU bus frequencies are not
guaranteed to be stable. Overclocking the processor is not recommended,
as it may result in a slower speed.
