When adding system memory, you may install memory modules in any order. For optimum operation, Dell recommends installing the memory modules starting with socket A (closest to the top edge of the system board) and working toward socket D, leaving no open sockets between installed memory modules. Table 8-1 lists sample memory configurations. () %*"'

If a memory module is already installed in the socket you want to use, you must remove it. To do so, follow the instructions in “Removing a Memory Module.” Use the following procedure to install a memory module (see Figure 8-6): 1. Locate the plastic securing clips at each end of the socket. Press the clips out- ward until they snap open. 2. Orient the memory modules so that the cutouts on the bottom edge match the crossbars in the memory module socket slot, and pres
