To install DIMMs, follow these steps: 1. Observe the precautions in "Before You Begin" on page 3. 2. Turn off all peripheral devices connected to the computer. Turn off and unplug the computer. 3. Remove the computer cover and locate the DIMM sockets. 4. Remove the AGP video card (if it interferes with the DIMM clips from being easily opened and closed).
