upgrading and servicing the pc (2) 127
ddr dimms
DDR DIMMs must be 184-pin unbuffered DDR SDRAM (double data rate
synchronous dynamic random access memory). The PC ships with one or more
memory modules, but you can replace the existing memory module(s) with
higher-capacity ones. You can install 64 MB, 128 MB, 256 MB, or 512 MB
memory modules in the computer.
installing a memory module
1 Turn off the computer
and all peripherals.
2 Disconnect the
modem/telephone cable.
3 Disconnect the power
cable and all other
attached cables (such as
the keyboard, mouse, and
monitor).
4 Remove the side panel
and the fan duct (see
”removing the side panel”
on page 123 and ”removing the fan duct” on page 124).
5 Locate the memory sockets on the motherboard.
NOTE: If all of the memory sockets are filled, you need to remove one of the
memory modules (see ”removing a memory module” on page 128).
6 Move any cabling out
of the way, if
necessary.
7 Push down the two
retaining clips on the
ends of the memory
socket.
8 Holding the new
memory module by its
edges only, remove it
from the antistatic
packaging. (Avoid touching the memory chips or the gold contacts on the
module.) The memory module has one or two small notches on the lower
edge that fit into raised bumps in the memory socket.
9 Hold the memory module in alignment with the socket, aligning the notches
with the bumps.
10 Push straight down on top of the memory module until it is fully seated in the
socket. The retaining clips on the ends of the socket automatically lock it into
position when the memory module is fully seated.
