Removing Memory Modules

9Press 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.

When the memory module is properly seated in the socket, the ejectors on the memory module socket align with the ejectors on the other sockets that have memory modules installed.

10Repeat step 6 through step 9 of this procedure to install the remaining memory modules. See Table 3-1 or Table 3-2.

11Replace the cooling shroud assembly:

–If you are installing memory modules on the system board, see "Replacing the Cooling Shroud Assembly" on page 70.

–If you are installing memory modules on the PEM, see Figure 3-9.

12Replace the PEM. See "Replacing the PEM or PEM Shell" on page 76.

13Close the system. See "Closing the System" on page 66.

14Start up the system, press <F2> to enter the System Setup program, and check the System Memory setting on the main System Setup screen.

The system should have already changed the value to reflect the newly installed memory.

15If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 2 through step 14 of this procedure, checking to ensure that the memory modules are firmly seated in their sockets.

16Run the system memory test in the system diagnostics. See "Running the System Diagnostics" on page 167.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.
