DIP Switch 4:
Processor Speed
The red "DIP" switch labeled SW4
has four individual switches,
which are used to set the speed
of the processor.
The table on the right shows you
the switch settings for the various
speeds your processor may be
able to run at. (This table is also
silkscreened on the motherboard.)
Note: Most Intel processors have
a fixed Core/Bus ratio that over-
writes the setting of DIP Switch 4.
In most cases you do not need to
make any changes to SW4.
