2.7 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.
1. CPU frequency selection (DSW Switches 1-5)
This option tells the clock generator what frequency to send the CPU,
and to the AGP and PCI slots. This allows the selection of the CPU’s
external frequency (or Bus Clock).
Set the CPU frequency only to the recommended settings.
Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable.
