Installing a second microprocessor and heat sinkThe 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 Be extremely careful, the contacts are very fragile.v The server supports up to two Intel Xeon four-core, six-core, or eight-coremicroprocessors (depending on your model). To confirm that the server supportsthe microprocessor, see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ for a list of supported microprocessors.v Do not mix four-core, six-core, and eight-core microprocessors in the sameserver.v The microprocessor options that IBM supports are limited by the capacity andcapability of the server. Any microprocessor options that you install must havethe same specifications as the microprocessor(s) that came with the server.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 air baffle, the DIMM airbaffle, or the memory tray 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. See “Installing a memory module” on page 51 for details about theinstallation 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 Do not mix Intel Xeon ™ EX versions of the 6000 and 7000 Series and the E7Series microprocessors in the same server, it is not supported. In addition:– Intel Xeon EX versions of the 6000 and 7000 Series microprocessors aresupported only on machine types 7148 and 7149.– Intel Xeon EX E7 Series microprocessors are supported only on machine types7147 and 7192.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, so that you candetermine whether you have to update the server firmware. To download thelatest level of the server firmware and other code updates for your server, go tohttp://www.ibm.com/supportportal/.v If the thermal-grease protective cover (for example, a plastic cap or tape liner) isremoved from the heat sink, do not touch the thermal grease on the bottom ofthe heat sink or set down the heat sink. For details, see the information aboutthermal grease in the Problem and Determination Service Guide.Chapter 2. Installing optional devices 85
