4. Locate the memory module sockets in which you will remove memory modules.
Figure 6-9 shows the order of the memory module sockets.
5. Press down and outward on the ejectors on each end of the socket until the memory module pops out of the socket (see Figure 6-11).

Microprocessor Upgrades

To take advantage of future options in speed and functionality, you can add a second processor or replace either the primary or secondary processor.
NOTICE: The second processor must be of the same type and speed as the first processor.
Each processor and its associated L2 cache memory are contained in a PGA package that is installed in a ZIF socket on the system board. The following subsection
describes how to install or replace the microprocessor in either the primary or secondary processor socket.

Adding or Replacing a Microprocessor

In addition to the ZIF socket for the primary microprocessor on the system board, there is a second ZIF socket to accommodate a secondary microprocessor. The
secondary micro-processor must have the same operating frequency as the primary micro-processor. For example, if the system has a 933-MHz primary
microprocessor, your secondary microprocessor must also be a 933-MHz microprocessor.
In a single microprocessor system, the microprocessor must be installed in the primary ZIF socket.
The following items are included in the microprocessor upgrade kit:
A microprocessor chip
l
A heat sink
l
A securing clip
l
A VRM, if adding a second processor

NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
1. Open the front bezel (see "Removing the Front
2. Remove the system cover.
3. Remove the cooling shroud (see
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
4. Press down on the heat-sink securing clip to release the clip from the retaining tab on the ZIF socket (see Figure 6-12).
5. Remove the securing clip.
CAUTION: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to
