2-3. Installing System Memory
This motherboard provides four 184-pin DDR DIMM sites for memory expansion. The DDR DIMM
sockets support 8 M x 64 (64 MB), 16 Mx 64 (128 MB), 32M 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 3 GB
(Unbuffered)
or 3.5 GB
(Registered)
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,
following rules must be followed.
!
For those modules, we suggest that you be populate DIMM1 to DIMM4 in order.
!
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 PC1600 & PC2100
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.
