3-3. Installing System Memory
This motherboard provides four 184-pin DDR DIMM sites for memory expansion. The DDR SDRAM
DIMM sockets support 8 M x 64 (64 MB), 16M 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 SDRAM DIMM modules. Minimum memory is
64 MB and the maximum memory is 2 GB
(Unbuffered, Non-ECC PC 1600 and PC 2100)
or 3.5 GB
(Unbuffered, Non-ECC PC 2700 and PC 3200) DDR SDRAM. There are four memory module sockets
on the system board (for a total of eight banks). In order to create a memory array, the 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 2-5 to see what a 184-pin PC 1600, PC 2100
and 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 body.
Step 4. Locate your computer’s 184-pin memory expansion DDR DIMM socket.
