Upgrading the Microprocessor
To take advantage of future options in speed and functionality, you can upgrade the system microprocessor.
The microprocessor 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 upgrade or replace the microprocessor.
Replacing the Microprocessor
The following items are included in the microprocessor upgrade kit:
l A microprocessor
l A heat sink
l A securing clip
1. Remove the system cover (see " Removing the System Cover and Support Beam " in "Troubleshooting Your System").
2. Remove the cooling shroud (see " Removing the Cooling Shroud " in "Troubleshooting Your System").
3. Press down on the heat-sink securing clip to release the clip from the retaining tab on the ZIF socket (see Figure 6 -10 ).
4. Remove the securing clip.
Figure 6-10. Securing Clip
5. Remove the heat sink.
6. Pull the socket release lever straight up until the microprocessor is released (see Figure 6 -11 ).
NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
CAUTION: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to
maintain proper thermal conditions.
CAUTION: The microprocessor and heat sink can become extremely hot. Be sure the microprocessor has had sufficient time to cool before
handling.
