2-3. Installing System Memory

This motherboard provides three 184-pin DDR DIMM sites for memory expansion. The DDR DIMM sockets support 8 Mx64 (64 MB), 16 Mx64 (128 MB), 32 Mx64 (256 MB), 64 Mx64 (512 MB), and 128 Mx64 (1024 MB) or double density DDR DIMM modules. Minimum memory is 64 MB and the maximum memory is 2 GB (Unbuffered PC 2700 DDR Module) or 3 GB (Unbuffered PC 1600/2100 DDR Module) 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.

DIMM

Generally, installing DDR SDRAM modules to your motherboard is an easy thing to do. You can refer to Figure 2-4 to see what a 184-pin PC 1600, PC 2100 & 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.
