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 500 – 1G Hz processor.

Set System Bus Speed

SW1:							O : ON, X : OFF
CPU (MHz)	1	2	3	4	5	6	PCI(MHz)
Auto	X	X	X	X	O	O	33.3
66	O	O	X	X	X	X	33.3
75	O	O	O	X	X	X	37.5

140	X	X	O	O	X	X	35
150	X	X	O	X	X	X	37.5

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 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.
