Other trademarks and trade names may be used in this document to refer to either the entities claiming the marks and names or their products. Dell Computer Corporation disclaims any proprietary interest in trademarks and trade names other than its own.

This document provides instructions about adding or replacing microprocessors. To take advantage of future options in speed and functionality, you can add secondary microprocessors or replace microprocessors in your system.

NOTICE: Before you add or replace a microprocessor, check the latest system BIOS information on the Dell Support website at support.dell.com, and upgrade the BIOS if necessary.

Each microprocessor and its associated cache memory are contained in a pin-grid array (PGA) package that is installed in a ZIF socket on the system board. The following subsection describes how to install or replace the microprocessor in either the primary or secondary microprocessor sockets.

NOTE: In a single microprocessor system, the microprocessor must be installed in the primary microprocessor socket.

Adding or Replacing a Microprocessor

NOTICE: The secondary microprocessors must be of the same type and speed as the primary microprocessor. If the microprocessors are different speeds, they will operate at the speed of the slower microprocessor.

In addition to the ZIF socket for the primary microprocessor on the system board, other ZIF sockets might be present to accommodate secondary microprocessors.

The following items are included in the microprocessor upgrade kit:

• A microprocessor
• A heat sink
• Heat-sink retention clip(s)
• A VRM, used if adding a secondary microprocessor

Your upgrade kit may also include a cooling fan.

CAUTION: Before you perform this procedure, read the safety instructions in your System Information document.

1 Turn off the system, including any peripherals, and disconnect the power cable from the electrical outlet.
2 Open the system doors, or remove the system cover (see your Installation and Troubleshooting Guide).

CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in the System Information document.

3 Remove the cooling shroud, if applicable (see your Installation and Troubleshooting Guide).
4 If you are upgrading an existing microprocessor, remove the microprocessor heat sink.

NOTE: If a cooling fan is mounted on the heat sink, you can remove the heat sink without removing the fan. However, you can remove the fan to provide easier access to the heat-sink retention clip(s). For information on removing a cooling fan, see your Installation and Troubleshooting Guide.

a Remove the retention clip(s) securing the heat sink to the microprocessor by pressing down firmly on the retention clip tab, and then removing the clip from the heat sink.

See your system information label on the system cover for heat-sink retention clip information.

CAUTION: The microprocessor and heat sink can become extremely hot. Be sure they have had sufficient time to cool before handling.

NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to maintain proper thermal conditions.

NOTICE: After removing the heat sink, place it upside down on a flat surface to prevent the thermal interface material from being damaged or contaminated.

b Remove the heat sink. See your Installation and Troubleshooting Guide for information on removing the heat sink.

5 Swing the socket release lever upward to the fully open position (see Figure 1-1).

NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending the pins can permanently damage the microprocessor.

6 Lift the microprocessor out of the socket and leave the release lever in the open position so that the socket is ready for the new microprocessor.

NOTICE: Be careful not to bend any of the pins when unpacking the microprocessor. Bending the pins can permanently damage the microprocessor.

7 Unpack the new microprocessor.

If any of the pins on the microprocessor appear bent, see "Getting Help" in your Installation and Troubleshooting Guide for instructions about obtaining technical assistance.

NOTICE: Positioning the microprocessor incorrectly can permanently damage the microprocessor and the system when you turn on the system. When placing the microprocessor in the ZIF socket, be sure that all of the pins on the microprocessor go into the corresponding holes. Be careful not to bend the pins.

8 Install the microprocessor in the socket (see Figure 1-1).

a Ensure that the microprocessor socket release lever is in the fully open position.

b Align pin 1 on the microprocessor with pin 1 on the microprocessor socket.

c With pin 1 of the microprocessor and socket aligned, set the microprocessor lightly in the socket and ensure that all pins are matched with the correct holes in the socket.

Because the system uses a ZIF microprocessor socket, there is no need to use force (which could bend the pins if the microprocessor is misaligned). When the microprocessor is positioned correctly, it should drop down into the socket with minimal pressure.

d When the microprocessor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, locking the microprocessor in the socket.

9 Install the heat sink.

• If the heat sink provided has a foil thermal interface material strip on the bottom of the heat sink, place the heat sink on the microprocessor.
• If the heat sink provided has a thermal grease tab, remove the tab and place the heat sink on the microprocessor.
• If heat-sink thermal grease is provided, clean the heat sink and apply the thermal grease before placing the heat sink on the microprocessor.

See your system information label on the system cover for the correct heat sink orientation.

NOTICE: To avoid possible damage to the microprocessor, you must align the heat sink so that the triangular mark on the heat sink points toward the triangular mark on the system board, if applicable.
10 Orient the heat-sink retention clip as shown in your Installation and Troubleshooting Guide.
11 Hook the end of the clip without the release tab over the tab on the edge of the socket.
12 Press down on the release tab until the hole on the clip latches onto the ZIF socket tab.
NOTICE: If a cooling fan is provided with your upgrade kit, you must install the fan on the microprocessor heat sink to provide proper thermal conditions. For information on installing a cooling fan, see your Installation and Troubleshooting Guide.
13 If a cooling fan is provided with your upgrade kit or if you removed a cooling fan earlier in this procedure, install the fan on the microprocessor heat sink.
14 Install the VRM(s):

a If you are adding a secondary microprocessor, examine the VRM to ensure that it is the correct VRM for your system.

b Insert the VRM in the appropriate secondary VRM connector, ensuring that the latches at each end of the connector engage (see Figure 1-2).

c If you received two VRMs with the upgrade kit, replace the primary VRM already installed in the system with one of the VRMs from the upgrade kit.

NOTE: The system does not support mismatched VRMs.

15 Replace the cooling shroud, if applicable (see your Installation and Troubleshooting Guide).

16 Close the system doors, or replace the system cover (see your Installation and Troubleshooting Guide).

17 Reconnect your system and peripherals to their electrical outlets, and turn them on. As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup program.

NOTE: After you access the inside of the system, the chassis intrusion detector will cause an alert message to be displayed at the next system startup. This message is stored in the system's nonvolatile random-access memory (NVRAM). To clear this message log, see your systems management software documentation.

18 Enter the System Setup program and ensure that the microprocessor categories match the new system configuration. For instructions about using the System Setup program, see your User's Guide.
