See the manufacturer's documentation and your Microsoft® Windows® documentation for more information. Memory You can increase memory up to 1 gigabyte (GB) by using synchronous dynamic random-access memory (SDRAM) dual in-line memory modules (DIMMs). The system board illustration shows the location of the DIMM sockets on the system board. (DIMMs may either be error checking and correction [ECC] or non-error checking and correction [non-ECC]. However, all DIMMs must be the same type of memory-either ECC or non-ECC.) When you add memory, you may install DIMMs in either socket. For optimum operation, Dell recommends that you install a DIMM in socket A first (closest to the processor) before installing a DIMM in socket B. Installing DIMMs CAUTION: To avoid the possibility of electric shock, turn off the computer and any devices, disconnect them from their electrical outlets, and then wait 10 to 20 seconds before you open the computer cover. Also, before you upgrade memory, see the other precautions in "CAUTION: Safety Instructions." 1 Open the computer cover. 2 If necessary, remove any DIMMs that occupy sockets in which you plan to install the upgrade memory modules. 3 Install the upgrade DIMMs. a Press the securing clips at each end of the socket outward until they snap open. b Align the slots on the bottom of the memory module with the ridges inside the socket. 88 Installing Upgrades
