ET900 User’s Manual
The ET900 COM Express CPU module accommodates 200-pin
DDR2-533 and DDR2-667 SODIMM memory modules with capacities
up to 1GB. Non-ECC is supported.
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module align
with those on the memory slot. Insert the module into the socket at a
slight angle (approximately 30 degrees). Note that the socket and
module are both keyed, which means that the module can be installed
only in one direction.
2. To seat the memory module into the socket, apply firm and even
pressure to each end of the module until you feel it slip down into the
socket.
3. With the module properly seated in the socket, rotate the module
downward. Continue pressing downward until the clips at each end
lock into position.
4. To remove the DDR2 module, press the clips with both hands.
