3. HARDWARE SETUP
2) CPU External Frequency Selection (DIP_SW Switches 5–8)
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 frequency (the advertised CPU speed).
3. H/W SETUP
Motherboard Settings
WARNING! Set the CPU frequency 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. It may result in a slower speed.
