You must install at least one module in any of the three slots. Each module can be installed
with 128 MB to 1 GB of memory; total memory capacity is 2GB.
Do not remove any memory module from its antistatic packaging until you
are ready to install it on the motherboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear a
grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR SDRAM only.

notches and the DIMMs are keyed with cutouts so that they can only be
installed correctly.

in the DIMM slot.

correctly. The slot latches are levered upwards and latch on to the edges of
the DIMM.
