Installing an additional microprocessor and heat sink

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when you install a microprocessor
and heat sink:
v Be extremely careful. The microprocessor socket contacts are very fragile.
v The server base system board supports two microprocessors, and the optional
v A microprocessor air baffle must be installed whenever the two DIMM
v Microprocessors 3 and 4 must be installed as a pair on the optional
v Do not mix four-core, six-core, and eight-core microprocessors in the same
v The microprocessor options that IBM supports are limited by the capacity and
v You must always have a microprocessor in socket 1 on the system board.
v When one microprocessor is installed, the microprocessor air baffle, the DIMM
v When you install an additional microprocessor, you must also install additional

microprocessor and memory expansion tray provides two additional
microprocessor slots plus 24 additional DIMM connectors. The server supports
up to four Intel Xeon four-core, six-core, or eight-core microprocessors
(depending on your model) with the microprocessor and memory expansion
tray installed. To confirm that the server supports the microprocessor, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ for a
list of supported microprocessors.
connectors closest to the microprocessor (on the left and the right) are empty.
For example, when DIMM connectors 6 and 7 on the system board are empty, a
microprocessor air baffle must be installed on microprocessor 1. This is
applicable for all microprocessors.
