2 HARDWARE INSTALLATION
WARNING: Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD protection by
wearing an antistatic wrist strap and attaching it to a metal part of the
system chassis. If a wrist strap is unavailable, establish and maintain
contact with the system chassis throughout any procedures requiring
The system board is equipped with two 168-pin DIMM (Dual In-line Memory
Module) sockets that support VCM or PC SDRAM DIMM. PC SDRAM (Syn-
chronous Dynamic Random Access Memory) uses a fast memory interface
technology that includes using the clock on the chip to synchronize with the
CPU clock so that the timing of the memory chips and the timing of the CPU
are synchronized. This saves time during transmission of data, subsequently
increasing system performance.
Refer to Chapter 1 (System Memory section)
for detailed specification of the memory sup-
ported by the system board.
Installing the DIM Module
A DIM Module simply snaps into a DIMM
socket on the system board. Pin 1 of the DIM
module must correspond with Pin 1 of the
Pull the "tabs," located at the end of
the socket, to the side
Position the DIMM above the socket with the "notches" in the module
aligned with the "keys" on the socket.
Seat the module vertically into the socket. Make sure it is completely
seated. The tabs will hold the DIMM in place.
