• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as electrical connectors in the processor socket. Do not remove the grease cover from
a heat sink until you are instructed to do so.
Notes:
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.

server. All processors on the system board must have the same speed, number of cores, and frequency.
• Before you install a new PHM or replacement processor, update your system firmware to the latest level.
See "Update the firmware" on page 198.
• Installing an additional PHM can change the memory requirements for your system. See "Memory module
installation rules" on page 140 for a list of microprocessor-to-memory relationships.
• Optional devices available for your system might have specific processor requirements. See the
documentation that comes with the optional device for information.
• The PHM for your system might be different than the PHM shown in the illustrations.
