Installing a Memory Module

Upgrade the memory in your PC with memory of the same type and speed as the memory originally installed in your PC.

CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

1Open both latches of the memory module socket. See “Removing a Memory Module” on page 11.

•If you are replacing a memory module, put the new memory module in the same memory slot from which the old memory was removed.

Or

•If you are adding a memory module, install the new module into the socket nearest the preinstalled module, and install additional modules in the next available sockets.

2Hold 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.

3The 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.

4Replace any cabling that was removed.

Removing or Installing an Add-in Card

An add-in card is a circuit board, such as a PCI or an AGP card, that fits into a PC add-in card slot. Your PC contains several add-in card slots that can be used to add components to your PC. The PC component configurations vary by model.

WARNING: Do not overload the system by installing add-in cards that draw excessive current. The system is designed to provide 2 amps (average) of +5 V power for each board/card in the PC. The total +5 V current draw in a fully loaded system (one with all add-in card slots filled) must not exceed the total number of slots multiplied by 2 amps.

A Phillips screwdriver is needed to remove, replace, or add an add-in card.
