7.6Memory Modules

ÄCAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

ÄCAUTION: Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you discharge yourself of static electricity by briefly touching a grounded metal object. Refer to Chapter 5, “Identifying the Chassis, Routine Care, and Disassembly Preparation,” for more information.

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

1.Prepare the computer for disassembly (Section 7.1, “Preparation for Disassembly”).

2.Remove the computer access panel (Section 7.3, “Computer Access Panel”).

ÅWARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

3.Remove the front bezel (Section 7.4, “Front Bezel,”).

4.Rotate the drive cage to its full upright position.

5.Open both latches of the memory module socket 1, and insert the memory module into the socket 2. Begin by installing a module into the socket nearest the preinstalled module, and install the modules following the numerical order of the sockets.
