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.
Orient the heat-sink retention clip as shown in your Installation and Troubleshooting
10
Guide.
Hook the end of the clip without the release tab over the tab on the edge of the socket.

Press down on the release tab until the hole on the clip latches onto the ZIF
12
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.
If a cooling fan is provided with your upgrade kit or if you removed a cooling fan earlier
13
in this procedure, install the fan on the microprocessor heat sink.
If applicable, install the VRM(s):

If the heat sink provided has a protective cover on the underside of the heat sink,
remove and discard the cover to expose the thermal grease or foil thermal interface
material, and then 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.
If you are adding a secondary microprocessor, examine the VRM to ensure that it
is the correct VRM for your system.
Insert the VRM in the appropriate secondary VRM connector, ensuring that the
latches at each end of the connector engage (see Figure 1-2).
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.
