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
primar y 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.
