Memory Options - IBM System x3690 X5 At-A-Glance Reference Manual

Memory options

The IBM System x3690 X5 supports DDR3 memory. Memory is installed in DIMM sockets either on the
system planar (16 sockets) in an optional memory mezzanine tray (16 sockets). The DIMMs on the
system planar are directly connected to the first processor, and the DIMMs on the mezzanine are directly
connected to the second processor. If you install the mezzanine then you must install the second
processor. However the reverse is different: you do not have to install the mezzanine if you have two
processors installed (although for performance reasons the mezzanine is recommended).
The following table lists memory options available for x3690 X5 server and for the MAX5 memory
expansion unit.

The MAX5 supports a subset of the memory DIMMs listed as shown in the table. The 16 GB memory
options that are supported in the MAX5 as listed in the above table are only supported when it is the only
type of memory used in the MAX5. No other memory options can be used in the MAX5 if the 16GB DIMM
are used in the MAX5. This DIMM also supports redundant bit steering (RBS) when used in the MAX5 or
when used in x3690 X5 servers with E7 processors (machine type 7147).
The following memory protection technologies are supported:
ECC

ChipKill

Memory Mirroring

Memory Sparing

Redundant Bit Steering (MAX5 or servers with E7 processors only, x4 DIMMs only)
