Step 2 Install Memory Module
Your board comes with three DIMM sockets, providing support for up to
3GB of main memory using unbuffered DIMM modules from 64MB to
1GB. 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 100MHz
DRAM speed, use PC1600 memory; for 133MHz DRAM speed, use
PC2100 memory; for 166MHz speed, use PC2700 memory.
