Make sure that the memory you have is compatible with the motherboard as well as the
processor. For example, DDR200 and DDR266 memory modules can be used for
FSB=400MHz Intel Xeon processor but only DDR266 memory modules can be used for
FSB=533MHz Intel Xeon processor.

Memory Installation Procedure
When installing memory modules, make sure the modules align properly with the memory socket.
There should be a key (small indent) on your memory module that fits according to the key in the
memory socket. DDR modules and sockets have only one key, which is slightly off-center of the
module/socket. 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 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, then proceed with memory installation.

NOTE YOU MUST unplug the power supply before performing system hardwar e
changes in order to avoid damaging the board or expansion device.
