2.CPU External Frequency Selection (DSW Jumpers 1–5)

This option tells the clock generator which frequency to send to the CPU, DRAM and AGPclock. 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).

WARNING! 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.
