1. Due to two-way interleaving, installation of memory options in pairs is required. Standard RDIMMs are installed in sockets three and four.
One RDIMM pair is not required to match the other. Provides Error Checking and Correcting (ECC) via 16-bit Checksum Chipkill (corrects
1, 2, 3, or 4-bit errors on same chip and detects 2- through 8-bit errors contained in two chips).
2. IBM offers configure-to-order (CTO) capability for selected products through Easy Access. Although similar to machine type models
(MTM), CTO systems utilize different part numbers called Sales Building Blocks (SBB). The contents of an option may not entirely
correspond to an SBB because only a certain component within an option package may be required to configure a specific system.
Additional or different configuration rules or limitations may apply to the SBB. When a difference occurs, the rules will be documented in
the tables, diagrams or footnotes.

This table does not represent all possible memory configurations. Memory modules may vary in price per MB. Selection
of smaller RDIMMs may provide a more cost-effective alternative to using larger RDIMMs.
1. Network operating systems may limit the maximum amount of addressable memory. See operating system
specifications for further information.
2. Requires removal of standard memory. The system architecture supports up to 8GB total memory when 2GB RDIMMs
are available.
