Microprocessor Replacement
This document provides instructions on replacing the microprocessor
package on the Dell Precision™ WorkStation 530 computer.
NOTE: Dell recommends that only a technically knowledgeable person
perform this procedure.
NOTE: Dell recommends that you read this entire document before you begin.
For more information on procedures in this document, see the
Service Manual
and
User’s Guide . You can access these documents from the Dell Precision
ResourceCD
or from the User’s Guides icon on your desktop if you have not
reinstalled your operating system.
Precautionary Measures
CAUTION: Before you remove the computer cover, perform the
following steps in the sequence indicated.
1Turn off your computer and any devices.
Disconnect your computer and devices from their power sources. Also,
disconnect any telephone or network lines from the computer.
Doing so reduces the potential for personal injury or shock.
2If you are disconnecting a device from the computer or are removing a
component from the system board, wait 10 to 20 seconds after
disconnecting the computer from AC power before disconnecting the
device or removing the component to avoid possible damage to the
system board.
3Wear a wrist grounding strap, and clip it to an unpainted metal
surface, such as the padlock loop on the back of the chassis. If a wrist
grounding strap is not available, touch any unpainted metal surface on
the back of the computer or on the computer chassis, such as the
power supply, to discharge any static charge from your body before
touching anything inside the computer. While you work, periodically
touch an unpainted metal surface on the computer chassis to dissipate
any static electricity that might harm internal components. Also avoid
touching components or contacts on a card and avoid touching pins on
a chip.

4Verify that the standby power light on the system board is not on. If it
is on, you may need to wait 10 to 30 seconds for it to go out.
Microprocessor Installation Guidelines
• A voltage regulator module (VRM) must be installed for each
microprocessor installed. To locate the VRM and microprocessor
sockets, see "System Board Components" or "Interior Service Label" in
your User’s Guide.
• For single-processor operations, the processor must be installed in
socket 0 and the VRM must be installed in connector 0. Processor
socket 1 and VRM connector 1 must be empty. To locate these
components, see "System Board Components" or "Interior Service
Label" in your User’s Guide.
• For dual-processor operations, both processor sockets and both VRM
connectors must be populated.
• For dual-processor operations, the two processors and the two VRMs
must be identical. If the processors do not match, you receive a system
message, the diagnostic lights indicate an error, and the computer may
not start. If the VRMs do not match, the diagnostic lights will indicate
an error.
• If installing a Dell™ processor upgrade kit for either single or dual
processors, remove and discard the original VRM(s). Then install the
VRM(s) from the upgrade kit. If you are not installing a processor
upgrade kit from Dell, reuse the original VRM(s).
• If installing a Dell processor upgrade kit for either single or dual
processors, remove and discard the original heat sink(s) and securing
clips. Then install the heat sink(s) and securing clips from the upgrade
kit. If you are not installing a processor upgrade kit from Dell, reuse the
original heat sink(s) and securing clips.

Upgrading the Microprocessor(s)
. NOTE: Dell recommends that only a technically knowledgeable person
perform this procedure.
CAUTION: The processor can get very hot during normal
operation. Be sure that the processor has had sufficient time to
cool before you touch it.
CAUTION: Before you perform this procedure, see “Precautionary
Measures."
NOTICE: Before disconnecting a device from the computer, wait 10 to
20 seconds after disconnecting the computer from its electrical outlet. Before
removing a component from the system board, verify that the standby power
light on the system board has turned off. To locate this light, see "System Board
Components" or "Interior Service Label" in your
User’s Guide .
1Remove the microprocessor airflow shroud:
aLay the computer on its right side.
bOpen the computer cover.
cPress down and back on the indentations at the top corners of the
shroud.

Removing the Microprocessor Airflow Shroud
dLift the airflow shroud out of the chassis.
2Remove the microprocessor heat sink:
aFor each of the metal clips that secure the heat sink to the
microprocessor, press down on the clip’s latch to release it from
the heat-sink retention base. Then lift the clip away from the heat
sink.
bLift the heat sink away from the microprocessor.
