Upgrading the Microprocessor
To take advantage of future options in speed and functionality, you can replace the microprocessor on your
system board with any Dell-supported microprocessor upgrade. Call your Dell sales representative for
information on available microprocessor upgrades.
The microprocessor upgrade kit includes a new single-edge contact (SEC) cartridge with heat sink assembly.
CAUTION: Before you remove the computer cover, see " Safety First — For You and Your
Computer ."
The following procedure describes how to replace the microprocessor.
NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
1. Remove the computer cover according to the instructions in " Removing the Computer Cover ."
CAUTION: The SEC cartridge and heat sink can get extremely hot during system
operation. Be sure the assembly has had sufficient time to cool before you touch it.
2. Locate the SEC cartridge connector (labeled "SLOT1") and the microprocessor fan connector (labeled
"FAN") on the system board.
See Figure 1 .
3. Disconnect the microprocessor fan cable from the connector on the system board.
4. Remove the SEC cartridge/heat sink assembly from the system board connector (see
Figure 10 ).
Press outward and hold the guide-bracket assembly latches, grasp the SEC cartridge/heat sink
assembly firmly, and pull away from the connector on the system board. Lift the SEC cartridge/heat
sink assembly from the guide bracket assembly.
NOTE: You must use up to 15 pounds of force to disengage the SEC cartridge from the
connector.
