3-3. Installing System Memory

This motherboard provides two 184-pin DDR DIMM sites for memory expansion. The DDR DIMM
sockets support 8 M x 64 (64 MB), 16 M x 64 (128 MB), 32 M x 64 (256 MB), 64 M x 64 (512 MB), and
128 M x 64 (1024 MB) or double density DDR DIMM modules. Minimum memory is 64 MB and the
maximum memory is 2 GB (Unbuffered & Non-ECC PC 1600/2100/2700 DDR Module) DDR
SDRAM. There are two memory module sockets on the system board (for a total of four banks). In order
to create a memory array, following rules must be followed.
Supports single and double density DDR DIMMs.

Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 3-4 to see what a 184-pin PC 1600, PC 2100
& PC 2700 DDR SDRAM module looks like.
Unlike installing SIMMs, DIMMs may be
"snapped" directly into the socket. Note: Certain
DDR DIMM sockets have minor physical
differences. If your module doesn't seem to fit,
please do not force it into the socket as you may
damaged your memory module or DDR DIMM
socket.
The following procedure will show you how to
install a DDR DIMM module into a DDR DIMM
socket.
Step 1. Before you install the memory module,
please place the computer power switch in
the off position and disconnect the AC
power cord from your computer.
Step 2. Remove the computer's chassis cover.
Step 3. Before touching any electronic components,
make sure you first touch an unpainted,
grounded metal object to discharge any
static electricity stored on your clothing or
