Installing and Removing RAM
The type of random access memory (RAM) your computer supports is referred to
as a DIMM (dual in–line memory module). DIMMs are available in many
configurations and specifications. When you decide to add RAM, be sure you
obtain the appropriate DIMMs for your computer’s system board. Refer to the
manual that comes with the system board to see whether the system board has
certain rules about installing the DIMMs.
To install a DIMM:
1. Turn off the computer and follow the other recommendations in the section
“Precautions to Follow Before Upgrading” on page 42.
2. Remove the system unit cover (see “Accessing the Interior of Your Computer”
on page 43).
3. Hold the DIMM above the socket.
4. Gently press the DIMM vertically into the socket as shown in Figure 5-2.
Apply equal pressure on each end of the DIMM.
NOTE
DIMMs are keyed to prevent them from being inserted the wrong way.
5. Make sure the clamps on both sides of the socket have locked the DIMM into
place. The DIMM should be standing straight up.
