Installing memory modules
Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. You should only
perform troubleshooting and simple repairs as authorized in your product documentation, or as
directed by the online or telephone service and support team. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow the safety instructions
that came with the product.
1. Ensure that you read the Safety instructions.
2. Follow the procedure listed in Before working inside your system.
3. Remove the cooling shroud.
4. Removing the cooling-fan assembly.
WARNING: The memory modules are hot to the touch for some time after the system has been
powered down. Allow time for the memory modules to cool before handling them. Handle the
memory modules by the card edges and avoid touching the components or metallic contacts on
the memory module.
CAUTION: To ensure proper system cooling, memory-module blanks must be installed in any
memory socket that is not occupied. Remove memory-module blanks only if you intend to install
memory modules in those sockets.
Steps
1. Locate the appropriate memory-module socket.
CAUTION: Handle each memory module only by the card edges, making sure not to touch
the middle of the memory module or gold contacts.
2. If a memory module or a memory-module blank is installed in the socket, remove it.
NOTE: Retain the removed memory-module blank(s) for future use.
CAUTION: To prevent damage to the memory module or the memory-module socket during
installation, do not bend or flex the memory module; insert both ends of the memory module
simultaneously.
3. Align the edge connector of the memory module with the alignment key of the memory module
socket, and insert the memory module in the socket.
NOTE: The memory-module socket has an alignment key that allows you to install the memory
module in the socket in only one orientation.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both
ends of the memory module evenly.
4. Press the memory module with your thumbs until the socket levers firmly click into place.
