Installing the memory
The IB939 board supports two DDR3 memory socket for a maximum total memory of
8GB in DDR3 SO-DIMM memory type.
Installing and Removing Memory Modules
To install the DDR3 modules, locate the memory slot on the board and perform the
following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligns with that 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 DDR3 module, press the clips with both hands.
