Installing a processor

* 
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.
3.
Keep the Phillips #2 screwdriver ready.
4.
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.
5.
Remove the cooling shroud.
* 
NOTE: If applicable, close the expansion card latch on the cooling shroud to release the full length card.
6.
If connected, disconnect the cables from expansion card(s).
7.
If installed, remove the expansion card riser.
* 
NOTE: The heat sink and processor are too hot to touch for some time after the system has been powered down. Allow the heat sink and processor to cool down before handling them.
* 
CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.
* 
NOTE: If you are installing a single processor, it must be installed in socket CPU1.
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 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 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 system board.
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 lock icon and push it under the tab to lock it.
12.
Similarly, lower the open first socket-release lever near the unlock icon unlock icon and push it under the tab to lock it.

NOTE: Ensure that you install the heat sink after you install the processor. The heat sink is necessary to maintain proper thermal conditions.
1.
Install the heat sink.
2.
If removed, reinstall the PCIe expansion card riser.
3.
If disconnected, reconnect the cables to the expansion card(s).
4.
While booting, press F2 to enter System Setup and verify that the processor information matches the new system configuration.
5.
Run the system diagnostics to verify that the new processor operates correctly.

4.
Install the processor.
* 
NOTE: If you are installing a single processor, it must be installed in socket CPU1.
1.
If you are using an existing heat sink, remove the thermal grease from the heat sink by using a clean lint-free cloth.
2.
Use the thermal grease syringe included with your processor kit to apply the grease in a thin spiral on the top of the processor.
* 
CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
* 
NOTE: The thermal grease syringe is intended for one-time use only. Dispose of the syringe after you use it.

3.
Place the heat sink onto the processor.
4.
Tighten one of the four screws to secure the heat sink to the system board.
5.
Tighten the screw diagonally opposite to the first screw you have tightened.
* 
NOTE: Do not over-tighten the heat sink retention screws when installing the heat sink. To prevent over-tightening, tighten the retention screw until resistance is felt, and stop after the screw is seated. The screw tension should not be more than 6 in-lb (6.9 kg-cm).
6.
Repeat the procedure for the remaining two screws.
1.
Follow the procedure listed in the After working inside your system section.
2.
While booting, press F2 to enter System Setup and verify that the processor information matches the new system configuration.
3.
Run the system diagnostics to verify that the new processor operates correctly.

PCIe card holder

Removing the PCIe card holder
Installing the PCIe card holder
Opening and closing the PCIe card holder latch

The PCIe card holder can be extended to support a full length PCIe card. This will prevent any damage to the card that may occur due to its length.

Removing the PCIe card holder

1.
Follow the safety guidelines listed in the Safety instructions section.
2.
Follow the procedure listed in the Before working inside your system section.
3.
If installed, remove the full-length PCIe card.
* 
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.

CAUTION: Do not use your system without the PCIe card holder installed. The PCIe card holder is necessary to ensure proper system cooling.
1.
Press the release tab and slide the card holder toward the back of the chassis to release the PCIe card holder from the chassis.
2.
Lift the PCIe card holder out of the chassis.
* 
NOTE: To ensure proper system cooling, you must replace the PCIe card holder.
