Installing a processor
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 are shipped with your product.
1. If you are upgrading your system, download the latest system BIOS version from Dell.com/support and follow the
instructions included in the compressed download file to install the update on your system.
NOTE: You can also update the system BIOS by using the Dell Lifecycle Controller.
2. Remove the cooling shroud.
NOTE: If applicable, close the expansion card latch on the cooling shroud to release the full length card.
3. If connected, disconnect the cables from expansion card(s).
4. If installed, remove the expansion card riser.
NOTE: If you are installing a single processor, it must be installed in socket CPU1.
Steps
1. Unpack the new processor.
NOTE: If the processor has previously been used in a system, remove any remaining thermal grease from the processor
by using a lint-free cloth.
2. Locate the processor socket.
3. If applicable, remove the socket protective cap.
4. Release the open first socket-release lever near the unlock icon by pushing the lever down and out from under the tab.
5. Similarly, release the close first socket-release lever near the lock icon by pushing the lever down and out from under
the tab. Lift the lever 90 degrees upward.
6. Hold the tab near the lock symbol on the processor shield and lift it up and out of the way.
CAUTION:
Positioning the processor incorrectly can permanently damage the system board or the processor.
Be careful not to bend the pins in the socket.
CAUTION: While removing or reinstalling the processor, wipe your hands of any contaminants. Contaminants
on the processor pins such as thermal grease or oil can damage the processor.
7. Align the processor with the socket keys.
CAUTION:
Do not use force to seat the processor. When the processor is positioned correctly, it engages
easily into the socket.
8. Align the pin-1 indicator of the processor with the triangle on the socket.
9. Place the processor on the socket such that the slots on the processor align with the socket keys.
10. Close the processor shield.
11. Lower the close first socket-release lever near the lock icon and push it under the tab to lock it.
