FJ1 Table:

FJ1	Available multiplier in the “DRAM:CPU multiplier”
	option
1-2 (default)	Auto detect
2-3	1.33
Open	1.00 / 1.25 / by SPD

Your memory frequency is dependent on your CPU front side bus frequency. It is calculated by:

Memory frequency. = DRAM multiplier (set in the CMOS setup) * CPU front side bus frequency * 2

Note:

•If you plan to use the memory at the default speed, set the FJ1 to 1-2 (auto detect)

•When using a 400MHz CPU, you need to set the FJ1 to 2-3 or 1-2. Setting FJ1 to open will not allow your system to boot-up.

•When using a 533MHz CPU, you can set FJ1 to 1-2, 2-3 or open, depending on the memory frequency you wish to use.

Example:

1.A system using a 400MHz CPU and a PC2100 memory module with FJ1 set as 1-2 or 2-3. Your current memory frequency is

400MHz /4= 100MHz * 1.33 = 133MHz *2 (since it is a DDR module) = 266MHz

2.A system using a 533MHz CPU and a PC2700 memory module with FJ1 set as open. The multiplier in the “DRAM:CPU Ratio” option in the bios is set to 1.25, your current memory frequency will be

533MHz /4=133 MHz* 1.25 = 166MHz * 2 (since it is a DDR module) = 333MHz

Step 3. Connect cables, case wires, and power supply Install expansion cards

This section tells how to connect internal peripherals and the power supply to the Motherboard.

The internal peripherals consist of IDE devices (HDD, CD-ROM), Floppy Disk Drive, Chassis Fan, Front Panel Devices (ACPI LED, Internal Speaker, Reset Button, IDE LED, and KeyLock Switch.), Wake-On-LAN card, VGA card, Sound Card, and other devices.

For more details on connecting internal and external peripherals to your new SY-P4I845PE Lite Motherboard, please refer to SY-P4I845PE Lite Motherboard User's Manual and Technical Reference online manual on the CD-ROM.
