CPU SPEED SETUP
The system bus frequency can be switched between 66MHz and 133MHz
by adjusting DIP SW2. The CPU frequency ratio can be switched from X3
to X8 by adjusting DIP SW1. The user can set up CPU speed for
366~533MHz processors by adjusting SW1 and SW2 properly.
M
The CPU speed must match with the frequency RATIO. It will
cause system hanging up if the frequency RATIO is higher than that
of CPU.

«Note: Please set the CPU host frequency in accordance with your
processor’ s specifications. We don’ t recommend you to set
the
system bus frequency over the CPU’ s specification because
these specific bus frequencies are not the standard
specifications for CPU, chipset and most of the peripherals.
Whether your system can run under these specific bus
frequencies properly will depend on your hardware
configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
