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.

For Auto Jumper Setting: SW1 ON 1 2 3 4 5 6 . Note: 1. If you use 66/100/1333 MHz CPU, We recommend you to setup your system speed 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 are not the standard specifications 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 configurations: CPU, SDRAM, Cards, etc. 1.
