Installing System Memory
There are two system memory sockets on the
motherboard. They use 3.3Volt, non-buffered
SDRAM DIMMs (Dual In-line Memory Module).
This motherboard uses either PC100 or PC133
DIMMs. The motherboard will automatically de-
tect and configure the installed memory. This
means you can use PC100 memory even if the
external 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
sections divided by spacers with a crossbar. The
crossbars 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 memory, you should take precautions
against static electric damage to sensitive compo-
nents on the modules and the motherboard. To
install a module does as follows:
1.
Press the socket retaining latches down to cre-
ate 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 mo d-
ule and the socket are lined up correctly.
