Installing a microprocessorThe following notes describe the type of microprocessor that the server supportsand other information that you must consider when you install a microprocessor:v Microprocessors are to be installed only by trained service technicians.v Always use the microprocessor installation tool to install a microprocessor. Failingto use the microprocessor installation tool may damage the microprocessorsockets on the system board. Any damage to the microprocessor sockets mayrequire replacing the system board.v To confirm that the server supports the microprocessor that you are installing,see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v The server supports up to two or up to four multi-core AMD Opteron ™microprocessors. If you are installing two or more microprocessors, they must bethe same cache size and type, and the same clock speed.v The server can operate as a symmetric multiprocessing (SMP) server. With SMP,certain operating systems and application programs can distribute the processingload among the microprocessors. This enhances performance for database andpoint-of-sale applications, integrated manufacturing solutions, and otherapplications.v Read the documentation that comes with the microprocessor to determinewhether you have to update the IBM System x Server Firmware (serverfirmware). To download the most current level of server firmware, go tohttp://www.ibm.com/systems/support/.v Obtain an SMP-capable operating system. For a list of supported operatingsystems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.v As of the date of this document, SUSE Linux Enterprise Server 11 Service Pack1 does not support XEN virtualization on a server using AMD Opteron 6200series microprocessors.v You can use the Setup utility to determine the specific type of microprocessor inthe server.v Each microprocessor socket must always contain either a socket dust cover or amicroprocessor and heat sink.v The pins on the sockets are fragile. Any damage to the pins might requirereplacing the system board.v Populate the microprocessor sockets in the following order: 1, 2, 3, 4. Thefollowing illustration shows the locations of the microprocessor sockets on thesystem board.64 IBM System x3755 M3 Type 7164: Installation and User’s Guide
