Installing System Components
NOTICE:
You must position the processor correctly in the socket to avoid damaging the processor and the system
board when you turn on the system. Be careful not to touch or bend the pins on the socket.
4 Set the processor lightly in the socket and ensure that the processor is level in the socket. When the
processor is positioned correctly, press it gently to seat it in the socket.
5 Close the processor cover.
6 Rotate the release lever back down until it snaps into place, securing the processor cover.
NOTICE:
Do not operate the system without the heat sink installed. The heat sink is required to maintain proper
thermal conditions.
7 Prepare the heat sink for installation:
• If you are reusing the heat sink from the previous processor, ensure that the contact side (bottom)
of the heat sink is clean, open the thermal grease packet, and apply thermal grease to the bottom
of the heat sink.
• If you received a replacement heat sink, remove the protective sheet from the thermal grease layer
that is pre-applied to the bottom of the heat sink.
8 Lower the heat sink onto the processor. See Figure 3-22.
9 Secure the heat sink to the retention module.
a Gently press down on the heat sink and then press one securing clip to secure it.
b Repeat step a for the remaining securing clip.
10 Ensure that the back fan connector is connected to the BACK_FAN connector on the system board.
See "System Board Connectors" on page 118.
11 Install the cooling shroud. See "Installing the Cooling Shroud" on page 65.
12 Close the system. See "Closing the System" on page 47.
13 Stand the system upright.
14 Reconnect the system to its electrical outlet and turn the system on, including any attached
peripherals.
15 Enter the System Setup program, and ensure that the processor options match the new system
configuration. See "Using the System Setup Program" on page 29.
As the system boots, it detects the presence of the new processor and automatically changes the system
configuration information in the System Setup program. A message similar to the following appears:
One 2.8 GHz Processor, Processor Bus: 533 MHz, L2 cache 256 KB
16 Confirm that the top line of the system data area in the System Setup program correctly identifies the
installed processor. See "Using the System Setup Program" on page 29.
17 Exit the System Setup program.
18 Ensure that your system is running the latest BIOS version.
You can download the latest BIOS version from the Dell Support website located at support.dell.com
