Installing Additional RAM Memory
The D4–470 comes equipped with 128MB of RAM. You do not need to add RAM
memory if 128MB of RAM is sufficient for your application.
The three 168–pin DIMM (Dual In–line Memory Module) sockets on the D4–470
support PC100–compliant SDRAMs. The sockets can be filled in any combination of
DIMMs of any size up to 768 MB of memory.
Prior to installing the DIMMs, first make sure the two handles of the DIMM socket are
in the open position (i.e. the handles lean outward). Slide the DIMM slowly along the
plastic guides on both ends of the socket. Then press the DIMM module straight
down into the socket until you hear a click. Note that the two DIMM socket handles
have automatically locked the memory module in place.
To remove the memory module, gently push the two handles outward
simultaneously. This will eject the memory from the DIMM socket.
