Asus P4B533 3.CPU external frequency selection (DSW1 Switches 1-6)

3.CPU external frequency selection (DSW1 Switches 1-6)

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 JEN jumper is set to jumper mode.
