CPU Speed Setup
The system bus speed is selectable at 66,100,133MHz and Auto. The user can select the system bus speed
(SW1) and change the DIP switch (SW2) selection to set up the CPU speed for 300 - 733MHz processor.
SW1:

133 33.3 X X X X X X

150 37.5 X X O X X X
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:
1. If you use 66, 100, 133 MHz CPU, we recommend you to set up your system speed to “Auto” value.
2. We don’t recommend you to set up your system speed to 112, 124, 142,152 MHz because these
frequencies are not the standard specifications for CPU, Chipset and most of the peripherals. Whether
your system can run under 112, 124, 142,152 MHz properly will depend on your hardware
configurations: CPU, SDRAM, Cards, etc.
