1.10 Switches and jumpers

The motherboard frequency is adjusted through the DIP switches. The white block represents the switch position. The illustration below shows the ON and OFF positions of the switches.

Make sure that the J6 jumper is set to pins 2-3 ( jumper mode) before setting the above switches.

The option to set the CPU core:bus frequency multiple is available only on unlocked CPUs. If you are using a locked CPU, setting the switches does not produce any effect.

1.CPU external frequency selection (SW1 Switches 1-5)

This option tells the clock generator what frequency to send the CPU. 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).

To select the CPU external frequency using the DIP switches, ensure that the J6 jumper is set to jumper mode.
