¡Note:° The STR LED is connected to the Voltage that feeds the DIMM sockets. Therefore the following table applies:

	Suspend to RAM	Normal Operation	Power Off
STR LED	ON	ON	OFF

Step 3. Configure Memory

Your board comes with three DIMM sockets, providing support for up to 1.5GB of main memory using unbuffered and registered DIMM modules from 8MB to 512MB. On this motherboard, DRAM speed can be set independent from the CPU front side bus speed. Depending on the DRAM clock speed setting in the BIOS setup, appropriate memory modules must be used. For 66MHz DRAM speed, use PC66 memory; for 100MHz DRAM speed, use PC100 memory; for 133MHz DRAM speed, use PC133 memory.

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.
