Memory options
IBM DDR3 memory is compatibility tested and tuned for optimal IBM System x® performance and
throughput. IBM memory specifications are integrated into the light path diagnostics for immediate system
performance feedback and optimum system uptime. From a service and support standpoint, IBM memory
automatically assumes the IBM system warranty, and IBM provides service and support worldwide.
The IBM System x3550 M4 supports DDR3 memory. The server supports up to 12 DIMMs when one
processor is installed, and up to 24 DIMMs when two processors are installed. Each processor has four
memory channels, and there are three DIMMs per channel.
The following rules apply when selecting the memory configuration:
Server supports UDIMMs (E5-2600 only), RDIMMs, and LRDIMMs.

Mixing different types of memory (UDIMMs, RDIMMs, and LRDIMMs) is not supported.


IBM System x3550 M4 17
Mixing 1.5 V and 1.35 V DIMMs in the same server is supported; in such cases, all DIMMs operate at

1.5 V.
The maximum number of ranks supported per one channel is eight (with the exception of Load

Reduced DIMMs, where more than eight ranks are supported because one quad-rank LRDIMM
provides the same electrical load on a memory bus as a single-rank RDIMM).
The maximum quantity of DIMMs that can be installed in server depends on number of CPUs, DIMM

type, rank, and operating voltage as shown in the "Maximum quantity" row in the following table.
All DIMMs in all CPU memory channels operate at the same speed, which is determined as the

lowest value of:
The memory speed supported by the specific CPU.

The lowest of maximum operating speeds for the selected memory configuration that depends on

rated speed, operating voltage, and quantity of DIMMs per channel, as shown under "Maximum
operating speed" section in the following table.
The following table (Parts 1, 2, and 3) shows the characteristics of the supported DIMMs. Tables cells
highlighted with a gray background indicate when the combination of DIMM voltage and the number of
DIMMs per channel still allows the DIMMs to operate at a rated speed.

The following memory protection technologies are supported:
ECC

Chipkill (for x4-based memory DIMMs)

Memory mirroring

Memory rank sparing

If memory mirroring is used, then DIMMs must be installed in pairs (a minimum of one pair per each
CPU), and both DIMMs in a pair must be identical in type and size.
If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank
DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing
mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank
varies depending on the DIMMs installed.
