2. Align the DIMM's edge connector with the slot in the center of the DIMM

the socket in only one way.
3. Press down on the DIMM with your thumbs while pulling up on the ejectors with
your index fingers to lock the DIMM into the socket (see Figure 8-5).
4. When the DIMM is properly seated in the socket, the ejectors on the DIMM

5. Repeat steps 1 through 3 of this procedure to install the remaining DIMMs.
6. Perform steps 4 through 8 of “Performing a Memory Upgrade” found earlier in
