1. IBM xSeries 440 architecture optimizes memory and bus performance using an XA-32 core chipset with up to two CPU/memory cards and two PCI-X host-bridge controllers. Up to
eight Pentium Xeon MP processors are supported. The recommended order of processor installation is shown in the accompanying diagrams. In models 1 ... 5RX, two processors are
standard with additional support for either two optional processors (total of four) or six optional processors (total of eight). In models 6RX and 7RX, four processors are standard and
four additional processors and an SMP module are required when upgrading. Eight processors require an xSeries SMP Expansion Module. Models 2RY and 3RY are limited to two
Xeon DP processors in each SMP Expansion Module, but can be upgraded by replacing the standard processors with Xeon MP processors.
2. A maximum of eight processors may be installed. All processors must be identical in type, speed and cache size. The fifth through eighth processors require an xSeries SMP
Expansion Module prepopulated with four processors (second SMP Expansion Module supported only when fully populated).
3. Requires removal of standard processors. A maximum of eight processors may be installed. Installation of greater than four processors requires the addition of an xSeries SMP
Expansion Module. All processors must be identical in type, speed and cache size. Upgrades may require a BIOS update. To obtain the latest Flash BIOS, access www.pc.ibm.com/
support and enter machine "Type-Model" in Quick Path. Select "Downloadable files" then "BIOS."
4. The fifth through eighth processors for models 1 ... 7RX require this option, which installs directly above the standard CPU/memory board. Two 250mm/10in scalability cables (P/N
24P1243) are included with the option. See SMP Expansion Module cabling diagrams below for scalability cabling configuration. Four CPUs are required with the optional SMP
Expansion Module for models 1 ... 7RX. A minimum of four RDIMMs installed in each SMP Expansion Module are required (not included). Memory mirroring requires a minimum of
eight RDIMMs in each SMP Expansion Module. This option is not compatible with models 3RY and 4RY. Models 1VX, 2VX and 3VX include two standard SMP Expansion Modules in
each chassis fully populated with a total of 16 processors (four in each of two SMP Expansion Modules for a total of eight in each chassis), one 250mm scalability cable (P/N
24P1243), two 2.5m scalability cables (P/N 73P6290), and an Ethernet crossover cable (used only in the absence of network connections for both chassis’).
5. Required to upgrade 3RY from two to the maximum of four Xeon DP processors. Memory options are not included. Both models 3RY and 4RY can be upgraded by replacing the
standard processors with Xeon MP processors. The same SMP Expansion Module is used, which supports up to four Xeon MP processors.
