Installing a second microprocessor and heat sinkUse this information to install a second microprocessor and heat sink.About this taskThe following notes describe the type of microprocessor that the server supportsand other information that you must consider when you install a microprocessorand heat sink:v Microprocessors are to be installed only by trained service technicians.Important: Always use the microprocessor installation tool to remove amicroprocessor. Failing to use the microprocessor installation tool may damagethe microprocessor sockets on the system board. Any damage to themicroprocessor sockets may require replacing the system board.v To confirm that the server supports the adapter that you are installing, seehttp://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Microprocessors are to be installed only by trained service technicians.v The server supports up to two Intel Xeon multi-core microprocessors.v Do not install an Intel Xeon ™ 5500 series microprocessor and an Intel Xeon ™5600 series microprocessor in the same server.v Do not mix dual-core, quad-core, and six-core microprocessors in the sameserver.v The first microprocessor must always be installed in microprocessor socket 1 onthe system board.v When one microprocessor is installed, a heat sink filler is not required formicroprocessor socket 2, however, the microprocessor 2 air baffle, the sixth fan,and the DIMM air baffle must be installed to provide proper system cooling.v Do not remove the first microprocessor from the system board when you installthe second microprocessor.v When you install the second microprocessor, you must also install additionalmemory and the sixth fan. See “Installing a memory module” on page 54 fordetails about the installation sequence.v To ensure proper server operation when you install an additionalmicroprocessor, use microprocessors that have the same QuickPath Interconnect(QPI) link speed, integrated memory controller frequency, core frequency, powersegment, internal cache size, and type.v Mixing microprocessors of different stepping levels within the same servermodel is supported.v When mixing microprocessors with different stepping levels within the sameserver model, you do not have to install the microprocessor with loweststepping level and features in microprocessor socket 1.v Both microprocessor voltage regulator modules are integrated on the systemboard.v If you have to replace a microprocessor, call for service.v Read the documentation that comes with the microprocessor to determinewhether you have to update the UEFI firmware. To download the most currentlevel of UEFI firmware for the server, go to http://www.ibm.com/support/fixcentral/.v The microprocessor speeds are automatically set for this server; therefore, youdo not have to set any microprocessor frequency-selection jumpers or switches.100 IBM System x3550 M3 Type 4254 and 7944: Installation and User's Guide
