NOTICE: If you are not installing a microprocessor upgrade kit from Dell,
reuse the original heat sink and securing clips when replacing the
microprocessor. There should be enough thermal grease remaining on the
bottom of the het sink to provide adequate thermal conductivity from the
microprocessor.
a
Lower the heat sink to the microprocessor so that the heat sink fits
in the heat sink retention base.
b
For each of the replacement metal clips that secure the heat sink
to the microprocessor, fit the end of the clip that does not have the
latch to the heat sink retention base. Then, press down on the
clip’s latch to secure the clip to the heat sink retention base (see
" Removing the Microprocessor Heat Sink ").
3
Replace the airflow shroud.
4
Rotate the power supply back into position until the securing tab
snaps into the release latch.
5
Replace the computer cover and restart the system .
6
Enter system setup, and confirm that the top line in the System Data
area correctly identifies the new microprocessor. Also, confirm that the
values under the
CPU Information
menu are correct for the new
microprocessor.
7
Exit system setup, and then run the Dell Diagnostics to verify that the
new microprocessor is operating properly.
