2-3. 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), 16M x 64 (128 MB), 32 M x 64 (256 MB) and 64 M x 64 (512 MB)
or double density DDR DIMM modules. Minimum memory is 64 MB and the maximum memory is 1 GB
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.
! The memory array is 64 or 72 bits wide. (Depending on with or without parity)
! For those modules, we suggest that you be populate DIMM1 to DIMM2 in order.
! Supports single and double density DDR DIMMs.

Step 4. Locate your computer's 184-pin memory expansion DDR DIMM socket.
Step 5. Insert the DDR DIMM module into the expansion socket as shown in the illustration. Note how
the module is keyed to the socket. You can refer to Figure 2-6 for the details. This insures the

Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 2-5 to see what a 184-pin PC 1600 and PC
2100 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,
Step 2. Remove the computer's chassis cover.
Step 3. Before touching any electronic components,

please place the computer power switch in
the off position and disconnect the AC
power cord from your computer.
make sure you first touch an unpainted,
grounded metal object to discharge any
static electricity stored on your clothing or
body.
