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.

Set System Bus Speed

SW1:					O : ON, X : OFF
CPU (MHz)	PCI(MHz)	JP6	1	2	3	4
66	33	1-2	X	X	O	O
100	33	1-2	X	X	X	X
112	37	1-2	O	X	X	X
124	41	1-2	O	O	X	X
133	33	N/C	O	O	O	X
142	35	N/C	X	O	O	X
152	38	N/C	O	X	O	X

The CPU sp eed must match with the frequency ratio. It will cause system hanging up if the frequency ratio is higher than that of CPU.

«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.
