1.4 Processors
The x440 models use one of the following processors:
Xeon Processor MP (“Gallatin”)
Xeon Processor MP (“Foster”)
Xeon Processor DP (“Prestonia”)
The Xeon MP models of the x440 come with two or four processors installed in
the standard SMP Expansion Module. Up to four processors are supported in the
standard module and, with the addition of a second SMP Expansion Module, up
to eight processors can be installed in an x440.
The x440 entry-level systems can be ordered with either two Xeon DP
processors in a single SMP Expansion Module or with four Xeon DP processors
in two SMP Expansion Modules. There is no further upgrade beyond four Xeon
DP processors, other than replacing them with Xeon MP processors.
See 3.1.1, “Processors” on page 64 for further discussion about what you should
consider before implementing an x440 solution.
