Memory Installation Procedure
When installing memory modules, make sure the modules align properly with the memory socket.
There should be keys (small indents) on your memory modules that fit according to the keys in the
memory socket. DDR modules and sockets have only one key, which is slightly near the center of
the module/socket. The SDR SDRAM modules and their sockets have two keys and will not insert
into DDR DIMM sockets. The method of installing memory modules is detailed in the following
diagrams.
Once the memory modules are firmly seated in the socket, two clamps on either side will close
and secure the module into the socket. Sometimes you may need to close the clamps manually.
To remove the memory module, simply push the clamps outwards until the memory module pops
up. Then simply remove the module.
TIP: When installing memory, a module may require a considerable amount of force to seat
properly, although this is very rare. To avoid bending and damaging your motherboard, place it on
its anti-static bag and onto a flat surface, and then proceed with memory installation.
YOU MUST unplug the power connector to the motherboard before performing
NOTE
system hardware changes, to avoid damaging the board or expansion device.
