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 chang e the DIP switch (SW2) selection to set up the CPU speed for 300 - 733MHz processor.

Set System Bus Speed SW1:

1. If you use 66/100/1333 MHz CPU, We recommend you to setup your system sp eed to “Auto” value.

2. We don’t recommend you to set up your system speed to 75 , 83 , 112 , 124 , 140 ,150 MHz because these frequencies a re not the standard specificatio ns for CPU, Chipset and most of the peripherals. Whether your system can run under 75 ,83 ,112 ,124 ,140 ,150 MHz properly will depend on your hardware configur ations: CPU, SDRAM, Cards, etc.
