SY-7IWMQuick Start Guide

Step 3. Configure Memory

Your board comes with three DIMM sockets, and provides support up to 512MB main memory using DIMM modules from 8MB to 256MB.

Memory Configuration Table

Number of	DIMM 1	DIMM 2	DIMM 3
Memory Modules
1	Double-sided/	Double-sided/
	Single-sided	Single-sided
2	Double-sided/	Single-sided	Single-sided²
	Single-sided
RAM Type		SDRAM¹
Memory Module Size (MB)		8/16/32/64/256 Mbytes

Note: 1. PC100 Compliant DIMM module is required regardless of 66 or 100 MHz FSB speed.

2.If you want to use DIMM3, DIMM2 must be used as well to let the system work properly. Just plugging a memory module into DIMM3 with DIMM2 left empty, will make the system unstable.

CMOS Clear (JP5)

In some cases the CMOS memory may contain wrong data, follow the steps below to clear CMOS memory.

1.Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. This jumper can be easily identified by its white colored cap.

2.Then put the jumper back to 1-2 to allow writing new of data into the CMOS memory.

CMOS Clearing	Clear CMOS Data			Retain CMOS Data
	Short pin 2-3 for			Short pin 1-2 to
JP5 Setting	at least 5 seconds to			retain new settings
	clear the CMOS

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