To replace a memory module, do the following:
1. Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
2. Remove the computer cover. See “Removing the computer cover” on page 90.
3. Locate the memory module you want to replace. The memory modules are installed in the memory slots
on the system board. See “Parts on the system board” on page 34.
4. Remove any parts that might prevent your access to the memory module. Depending on your computer
model, you might need to remove the PCI Express x16 graphics card for easier access to the memory
module. See “Replacing a PCI/PCI-Express card” on page 114.
5. Open the retaining clips and gently pull the memory module out of the memory slot.
