3. Remove the memory module cooling shroud (see " Removing the Microprocessor and Memory Module Cooling Shrouds ").
4. Locate the memory module sockets in which you will install a memory module. Figure 6 -8 shows the order of the memory module sockets.
5. Press down and outward on the memory module socket ejectors, as shown in Figure 6 -9 , to allow the memory module to be inserted into the socket.
Figure 6-9. Installing a Memory Module
6. Align the memory module's edge connector with the alignment keys, and insert the memory module in the socket (see Figure 6 -9 ).
The memory module socket has two alignment keys that allow the memory module to be installed in the socket in only one way.
7. Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the socket
(see Figure 6 -9 ).
When the memory module is properly seated in the socket, the memory module socket ejectors should align with the ejectors on the other sockets with
memory modules installed.
8. Repeat steps 4 through 7 of this procedure to install the remaining memory modules.
9. Perform steps 5 through 10 of " Performing a Memory Upgrade ."
Removing Memory Modules
1. Turn off the system, including any attached peripherals, and disconnect the AC power from the electrical outlet.
2. Remove the system's right-side cover (see " Removing the Side Covers " in "Troubleshooting Your System").
3. Remove the memory module cooling shroud (see " Removing the Microprocessor and Memory Module Cooling Shrouds ").
4. Locate the memory module sockets in which you will remove memory modules.
Figure 6 -8 shows the order of the memory module sockets.
5. Press down and outward on the memory module socket ejectors until the memory module pops out of the socket (see Figure 6 -10 ).

Microprocessor Upgrades
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary
microprocessor.
WARNING: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
" Safety First— For You and Your System " in "Troubleshooting Your System."
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
NOTICE: The second microprocessor must be of the same type and speed as the first microprocessor.
