Installing System Memory
There are two system memory sockets on the moth-
erboard. They use 3.3Volt, non-buffered SDRAM
DIMMs (Dual In-line Memory Module). This moth-
erboard uses either PC100 or PC133 DIMMs. This
means you can use PC100 memory even if the exter-
nal clock frequency used by the CPU is 66MHz. You
can install any size DIMM from 16MB to 256MB in
either socket in any order for a total of 512MB.
Installing DIMMs
The DIMM sockets have three edge connector sec-
tions divided by spacers with a crossbar. The cross-
bars match cut-outs in the DIMMs so that only the
correct type of module can be installed. The cutouts
vary by module type. Make sure you use the correct
module type as noted above. When installing mem-
ory, you should take precautions against static elec-
tric damage to sensitive components on the modules
and the motherboard. To install a module does as
follows:
1. Press the socket retaining latches down to create
full access to the socket.
2. Align the DIMM to the socket so that its edge
connector matches the socket’s connectors. The
three sections are of different lengths to make
the correct orientation obvious.
3. Lightly press the DIMM into the socket at a 90º
to the motherboard. Make sure the module and
the socket are lined up correctly.
