Installing System Components
4 Install the heat sink.
NOTE:
If you did not receive a replacement heat sink, use the heat sink that you removed in step 10.
a If you receive a heat sink and pre-applied thermal grease with your processor kit, remove the
protective sheet from the thermal grease layer on top of the heat sink.
If you did not receive a replacement heat sink with your processor kit, do the following:
• Using a clean lint-free cloth, remove the existing thermal grease from the heat sink you
removed in step 10.
• Open the grease packet included with your processor kit and apply thermal grease evenly to
the top of the processor.
b Place the heat sink on the processor. See Figure 3-28.
c Close one of the two heat sink retention levers until it locks. See Figure 3-28.
d Repeat for the other heat sink retention lever.
5 Reinstall the fan bracket. See "Replacing the Fan Bracket" on page 69.
6 Close the system. See "Closing the System" on page 55.
As the system boots, it detects the presence of the new processor and automatically changes the system
configuration information in the System Setup program.
7 Press <F2> to enter the System Setup program, and check that the processor information matches the
new system configuration. See "Entering the System Setup Program" on page 37.
8 Run the system diagnostics to verify that the new processor operates correctly.
See "Running the System Diagnostics" on page 132 for information about running the diagnostics.
