3-3. Installing System Memory
This motherboard provides three 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 3 GB (Unbuffered, Non-ECC PC 1600,PC 2100 and PC 2700) or
2 GB (Unbuffered, Non-ECC PC 3200) 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, the following rules must be
followed.
! When you install a DDR DIMM module fully into the DDR DIMM socket, the eject tab shouldbe
locked into the DDR DIMM module very firmly and fit into its indention on the both sides.
! We sugest you install DDR SDRAM modules from DIMM3 to DIMM1 sockets in order.
! When install two PC3200 DDR SDRAM modules, we sugest you install the two DDRSDRAM
modules into DIMM3 and DIMM2 sockets.
! Supports single and double density DDR DIMMs.

"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.

Note
Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 3-5 to see what a 184-pin PC 1600, PC 2100,
