2.7 Jumpers

The jumpers on the motherboard allow you to change some feature settings to suit your customized system configuration.

Motherboard Frequency Settings (FSJ Jumpers)

The motherboard frequency is adjusted through the FSJ jumpers.

Before changing any FSJ or jumper setting, make sure to read the jumper descriptions and setting requirements in this section.

1.CPU External Frequency Selection (FSJ1 Jumpers 1–5)

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