Adding Memory The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). The exact number of sockets depends on which model you have. To determine which type and speed of memory module your PC uses, and for specific memory module information and specifications, go to the Web site listed in your Warranty and Support Guide and click the Support link. WARNING: Using the wrong type of memory module could damage the system.
2 Hold the new memory module by its edges only as you remove it from the antistatic packaging. Avoid touching the memory chips or the gold contacts on the module. 3 The memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Push the module carefully and firmly into the slot, ensuring that the latches on both ends snap into place. WARNING: Do not overload the system by installing add-in cards that draw excessive current.
5 Loosen the screw on the card you are replacing. Hold the card at the top and carefully pull the card straight out of the add-in card slot. Installing an Add-in Card 1 Align the edge of the add-in card with the slot on the chassis and gently but firmly press the card straight down into the add-in card slot. The whole connector should be seated properly in the card slot. Replacing the Battery A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability.
