Removing DIMMs
To remove a memory module, follow these steps:
1. Observe the precautions in "Before You Begin" on page 23.
2. Turn off all peripheral devices connected to the computer. Turn off the computer.
3. Remove the AC power cord from the computer.
4. Remove the computer’s cover.
5. Remove the PCI Express x16 card if it interferes with the DIMM clips from being easily
opened and closed.
6. Gently spread the retaining clips at each end of the DIMM socket. The DIMM pops out of
the socket.
7. Hold the DIMM by the edges, lift it away from the socket, and store it in an anti-static package.
8. Reinstall and reconnect any parts you removed or disconnected to reach the DIMM sockets.
9. Replace the computer’s cover and reconnect the AC power cord.
Installing and Removing a PCI Express x16 Card
CAUTION
When installing an PCI Express x16 card on the desktop board, ensure that the card is fully seated
in the PCI Express x16 connector before you power on the system. If the card is not fully seated in
the PCI Express x16 connector, an electrical short may result across the connector pins.
Depending on the over-current protection of the power supply, certain board components and/or
traces may be damaged.
The PCI Express x16 connectors on the desktop board have an integrated card retention
mechanism (RM).
