3. Remove the cover (see " Removing the Cover ").
4. Remove the cooling shroud (see " Removing the Cooling Shroud ").
5. Locate the memory module connectors from which you will remove memory modules (see Figure 4-26 ).
6. Press down and outward on the memory module connector ejectors until the memory module pops out of the connector
(see Figure 4-27 ).
7. Repeat steps 4 through 6 of this procedure to remove any other memory modules.
8. Perform steps 6 through 11 of the procedure in " Performing a Memory Upgrade ."
Microprocessors
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the
primary or secondary microprocessor.
NOTE: The second microprocessor must be of the same type as the first. If the two microprocessors are different
speeds, both will operate at the speed of the slower microprocessor.
Each microprocessor and its associated cache memory are contained in a PGA package that is installed in a ZIF socket on the
system board. A second ZIF socket accommodates a secondary microprocessor.
NOTE: In a single microprocessor system, the microprocessor must be installed in the PROC 1 socket.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of
the components inside the system. See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against electrostatic discharge.
1. Open the bezel (see " Removing the Bezel ").
2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3. Remove the cover (see " Removing the Cover ").
