Step 2. Configure Memory

Your board comes with three DIMM sockets, and supports up to 512MB main memory using
industry standard Synchronous DRAM (SDRAM), single or double-sided, 3.3V unbuffered
DIMM modules from 8MB to 256MB. Registered DIMMs or DIMMs populated with 4 bit wide
SDRAM devices are not supported. PC100 compliant DIMM module is required regardless
of 66, 100 or 133 MHz FSB speed.

Note: 1. PC100 Compliant DIMM module is required regardless of 66, 100 or
133 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 not working.
