2-3. Installing System Memory

This motherboard provides three 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 1.5
GB DDR SDRAM. There are three memory module sockets on the system board (for a total of six 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 DIMM3 in order.
! Supports single and double density DDR DIMMs.

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.

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
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.
The following procedure will show you how to install a
DDR DIMM module into a DDR DIMM socket.
