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 poor performance and premature wearing of the processor.
4) CPU External Frequency Setting (SW1 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).
NOTE: The motherboard supports PC100 / PC133 DIMMs or VC SDRAMs
for system memory. Registered DIMMs are not supported (See 3.5 System
Memory, DIMM).
