CPU Speed Setup

The system bus speed is selectable at 66,100,133MHz and Auto. The user can select the
system bus speed (SW1)&JP6 and change the DIP switch (SW2) selection to set up the CPU
speed for 233 - 733MHz processor.

Note: 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.
