CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. 4 Move any cabling out of the way, if necessary. 5 Push down the two retaining clips on the ends of the memory socket until the memory module pops out of the socket. 1 Open both latches of the memory module socket: • If you are replacing a memory module, put the new memory module in the same memory slot from which the old memory was removed.

WARNING: Do not pull the memory module out of the socket. Use the retaining clips to eject the module. 6 Lift the memory module from the memory socket. 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. 2 The memory module can be installed in only one way.

Push the module carefully and firmly into the slot, ensuring that the latches on both ends snap into place. 3 Set the chassis upright. 4 Complete the procedures to replace the side panel, and close the PC. See "Opening and Closing the PC" on page 1.
