4.5 Installing the SDRAM Memory Module
You can install from 32 to 256 MB of SDRAM memory. The panel PC
system provides one 168-pin DIMM (Dual Inline Memory Module)
socket and supports 3.3 V SDRAM with a minimum speed of 12 ns.
Note: The module can fit into the socket only one way. Pin
1 of the DIMM module must line up with the small
arrowhead printed on the motherboard next to the
DIMM socket. The golden pins of the module must
point down into the DIMM socket.
1. Detach and remove the plastic rear cover and CPU cover.
2. Push the two white eject levers on each side of the DIMM outward
until they are separated from the black vertical posts. (See Fig. 4-4.)
3. Insert the memory module into the socket at an angle of 90 degrees.
4. Push the two eject levers toward the vertical posts at each end of
the socket until the module is upright.
