Step 6. Configure Memory

Your board comes with one SIMM Bank (2 modules) and two DIMM sockets, providing support for up to 512MB of main memory using DIMM modules from 8MB to 256MB. For 66MHz host bus CPUs use 12ns or faster DIMM modules; for 83MHz host bus CPUs use 8ns modules.

Memory Configuration Table

MEMORY	SIMM Bank	DIMM Banks
CONFIGURATION	Bank 1,2	DIMM 1	DIMM 2
RAM Type	FPM/EDO/BEDO	EDO/SDRAM	EDO/SDRAM
Single RAM	4/8/16/32/64	8/16/32/64/128/256	8/16/32/64/128/256
Module Size (MB)
Note: 1. You must install two SIMM modules to complete the SIMM Bank

2.Do not use FPM or EDO type of SIMM/DIMM if you already use SDRAM.

3.Do not install SIMM Bank and DIMM 1 at the same time.

Step 7. Clear CMOS

Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5, and then by shorting pin 1-2 to retain new settings. This jumper can be easily identified by its white colored cap.

CMOS Clearing	Clear CMOS Data		Retain CMOS Data
JP5 Setting	short pin 2-3 to	1	Short pin 1-2 to	1
		2		2
	clear the CMOS		retain new settings
		3		3

Note: You must unplug the ATX power cable from the ATX power connector when performing the CMOS Clear operation.
