Installing the Memory Board

Upgrades and Options
Notice: Use extreme care when removing a DIMM.
Hold DIMMs only by their edges. Place them on an
antistatic surface; do not slide them across any surface.
Applying too much pressure can break the retaining
clips or damage the socket slot. Apply only enough
pressure on the retaining clips to release the DIMM.
1. Remove the memory board as described earlier in
this section.
2. Remove the DIMM modules one at a time starting
from the highest numbered sockets.
3. To remove each DIMM, gently spread the retaining
clips (Figure 5-5, C) just enough so that you can pull
the top edge of the DIMM away from the clips.
4. Carefully lift the DIMM away from the socket and
store it in an antistatic package.
5. Repeat the above steps to remove the remaining
DIMMs.
6. Install the memory board back into the system as
described later in this chapter.
This procedure assumes you are reinstalling the
memory board you removed previously (see Removing
the Memory Board).
1. Be careful not to touch components or gold edge
connectors on the memory board as you remove it
from its protective wrapper.
2. On the system board, locate the memory board
connector (Figure 5-4, B).
3. Hold the memory board (see Figure 5-4, C) by its
edges and start to insert it into the slot guides.
