Installing memory modules

* 
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.
* 
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 are shipped with your product.
1.
Follow the safety guidelines listed in the Safety instructions section.
2.
Follow the procedure listed in the Before working inside your system section.
1.
Locate the appropriate memory module socket.
* 
CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts.
2.
Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
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.
* 
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory module evenly.
* 
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in only one orientation.
4.
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.

2.
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.

3.
If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory module is firmly seated in the memory module socket.
4.
Run the system memory test in system diagnostics.
