2-3. Installing System Memory

This motherboard provides two 168-pin DIMM sites for memory expansion. The DIMM
sockets support 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64 (64MB), 16Mx64
(128MB), and 32Mx64 (256MB) or double sided DIMM modules. Minimum memory size
is 8MB and maximum memory size is 256MB SDRAM (512MB using 128Mb technology).
There are two memory module sockets on the system board. (total four banks)
In order to create a memory array, certain rules must be followed. The following set of rules
allows for optimum configurations.
" The memory array is 64 or 72 bits wide. (Depending on with or without parity)
" Those modules can be populated in any order.
" Supports single and double density DIMMS.

Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can
refer to figure 2-5 to see what a 168-pin PC100 SDRAM module looks like.
If your module doesn't seem to fit, please do not force it into the socket as you may damaged
your memory module or DIMM socket.
The following procedure will show you how to install a DIMM module into a 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.

Unlike installing
SIMMs, DIMMs
may be "snapped"
directly into the
socket. Note:
Certain DIMM
sockets have minor
physical differences.
