ensure that the memory modules are firmly seated in their sockets.
10. Run the system memory test in the system diagnostics. See " Running the System Diagnostics ."
Removing Memory Modules
1. If you are removing memory in a hot-pluggable memory operating environment, remove the memory riser card as described in " Removing and Installing
a Hot-Pluggable Memory Riser Card ."
If you are removing memory in a non–hot-pluggable memory operating environment, remove the memory riser card as described in " Removing and
Installing a Non–Hot-Pluggable Memory Riser Card ."
2. Locate the memory module sockets. See Figure A -3 .
3. Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket. See Figure 6 -14 .
4. Install the memory riser card that you wish to upgrade. See " Removing and Installing a Hot- Pluggable Memory Riser Card ."
5. Close the system. See " Closing the System " in "Troubleshooting Your System."
Processor
You can upgrade the system processor(s) to take advantage of future options in speed and functionality, or add additional processors. Each processor and its
associated internal cache memory are contained in a pin grid array (PGA) package that is installed in a ZIF socket on the system board.
Removing a Processor
1. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See " Opening the System " in "Troubleshooting Your System."
3. Remove the cooling shroud. See " Removing the Cooling Shroud ."
4. While pressing firmly on the blue tab on the end of the heat-sink retention clip, compress the sides of the retention clip together until the clip
disengages from the slots in the socket, and then slide the retention clip forward to release it from the back clips. See
Figure 6 -15 .

NOTICE: When you remove the heat sink, the possibility exists that the processor might adhere to the heat sink and be removed from the socket. It is
recommended that you remove the heat sink while the processor is still warm.
NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper
thermal conditions.
