Microprocessor
You can upgrade the system processor to take advantage of future options in speed and functionality.
A processor upgrade kit contains the following items:
•
Processor
•
Thermal grease packet and/or a replacement heat sink
If your kit does not include a replacement heat sink, you must reuse the processor heat sink currently in your
system.
NOTICE:
If your upgrade kit included a thermal grease packet, you must use the thermal grease as instructed to
ensure the proper thermal operating condition for the processor. Failure to do so will result in damage to your
system.
