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.
