3. HARDWARE SETUP
WARNING! 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.
5) CPU External Frequency Setting (DSW Switches 1–5)
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).

3. H/W SETUP
IMPORTANT:
1. To use this feature, JEN must be set to Jumper Mode: [1-2]; [See section 1].
2. Otherwise, if JumperFree mode is enabled, use BIOS setup in place of these
switches (set Operating Frequency Setting to User Define under 4.4 Ad-
vanced Menu in BIOS Setup so you can set the CPU Frequency).
