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 After working inside your system.
  3. Remove the cooling shroud.
  4. Removing the cooling fan assembly.
NOTE:The memory modules are hot to touch for some time after the system has been powered down. Allow 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.

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 metallic contacts.
  2. If installed, remove the cooling fan assembly. For more information, see Removing the cooling-fan assembly.
  3. 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.
  4. 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.
  5. Press the memory module with your thumbs until the socket levers firmly click into place.

    When the memory module is properly seated in the socket, the levers on the memory module socket align with the levers on the other sockets that have memory modules installed.
  6. Repeat steps 4 and 5 of this procedure to install the remaining memory modules.

Next steps

  1. Install the cooling shroud.
  2. Follow the procedure listed in After working inside your system .
  3. Press <F2> to enter System Setup, and check the System Memory setting.

    The system should have already changed the value to reflect the installed memory.

  4. If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 4 through step 7 of this procedure, checking to ensure that the memory modules are firmly seated in their sockets.
  5. Run the system memory test in the system diagnostics.
