42 - Power Mac G5 Take Apart
Processor
Replacement Note: If you are replacing the processor with a new processor, do the
following:
• When removing the new processor from its packaging, be careful to lift the processor
straight up out of the box. Tilting the processor could damage the heatsink seal.
• Before installing the processor, remove the cap over the processor connector.
Warning: Do not remove the clear plastic strip on the bottom of the processor. Removing
the plastic could cause a short in the logic board.
Note: When installing the processor, place the first two screws diagonally from each other
and tighten part way. Replace the other two screws and tighten part way. Then tighten all
screws again until they are fully secured.
Important: Whenever you replace a processor with a new processor, you must run Apple
Service Diagnostic (once the computer is reassembled). You must also run the diagnostic
if you re-install the same processor but in a different connector from the one in which it
was originally installed. Apple Service Diagnostic for Power Mac G5 is available as a
download from the Disc Images section of the Apple Service Source website. For more
information, see “Thermal Calibration” in the Troubleshooting chapter.
