The computer should automatically recognize the additional memory the next time you turn on the

computer.

Expansion cards

The computer has two PCI Express x1 expansion slots, one PCI Express x16 expansion slot, and one PCI

Express x16 expansion slot that is downshifted to a x4 slot.

NOTE: You can install a PCI Express x1, x8, or x16 expansion card in the PCI Express x16 slot.

For dual graphics card configurations, the first (primary) card must be installed in the PCI Express x16 slot

that is NOT downshifted to a x4.

To remove, replace, or add an expansion card:

1. Prepare the computer for disassembly (

Preparation for disassembly on page 21)

2. Remove the access panel (

Access panel on page 22)

3. Remove the screw that holds down the expansion card retention latch (1) then slide the latch up (2) and

pull it off the rear of the chassis (3).

4. Locate the correct vacant expansion socket on the system board and the corresponding expansion slot

on the back of the computer chassis.

5. Before installing an expansion card, remove the expansion slot cover or the existing expansion card.

NOTE: Before removing an installed expansion card, disconnect any cables that may be attached to

the expansion card.

a. If you are installing an expansion card in a vacant socket, you must use a flatblade screwdriver to

pry out one of the metal shields on the rear panel that covers the expansion slot. Be sure to

remove the appropriate shield for the expansion card you are installing.
