CPU Speed Setup

The system bus speed is selectable at 66,100,133MHz. The user can select the system bus speed (SW1) and change the DIP switch (SW2) selection to set up the CPU speed for 500MHz – 1GHz and faster processor.

Set System Bus Speed

SW1/JP25:					O : ON, X : OFF
1	2	3	JP25	CPU(MHz)		PCI(MHz)
X	X	O	1-2	66		33
X	X	X	1-2	100		33
O	X	X	1-2	112		37

O	O	O	N/C	133		33
X	O	O	N/C	142		35
O	X	O	N/C	152		38

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.

0Intel Processor all have locked Frequency Multiple, so you can not change the CPU Frequency Multiple.

0For double CPU use, the same CPU must be used in CPU socket1 and 2. (The same stepping, FSB, ratio)

0 For single CPU use, use CPU socket1 only. Don’t use CPU socket2.

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.

Line Out 1: Line Out or SPDIF (The SPDIF output is capable of providing digital audio to external speakers or compressed AC3 data to an external Dolby digital decoder). In general, Line Out 1 is normally Line Out, when it output digital signal, it will be change to SPDIF Out automatically (see page 45 for more information).

Line In: In general, Line In is normally Line In. When you select “Four Speaker” in Creative application(see page 43 for more information), Line In will be change to Line Out 2, then you can plug 2 pairs stereo speaker into Line Out 1 and Line In simultaneously.
