System x3550 M5 14

Memory options

System x3550 M5 supports TruDDR4 Memory. TruDDR Memory uses the highest-quality components

sourced from Tier 1 DRAM suppliers and only memory that meets our strict requirements is selected. It is

compatibility tested and tuned on every System x server to maximize performance and reliability.

TruDDR4 Memory will have a unique signature programmed into the DIMM, which will enable System x

servers to verify whether the memory installed is qualified/supported. Because TruDDR4 Memory is

authenticated, certain extended memory performance features can be enabled to extend performance

over industry standards. From a service and support standpoint, System x memory automatically

assumes the system's warranty, and service and support provided worldwide.

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:

The server supports RDIMMs and LRDIMMs.



Mixing different types of memory (RDIMMs and LRDIMMs) is not supported.



The maximum quantity of DIMMs that can be installed in the server depends on the number of



processors.

All DIMMs in the server operate at the same speed, which is determined as the lowest value of the



following speeds:

Memory speed that is supported by the specific processor.



Lowest of maximum operating speeds for selected memory configuration that depends on



quantity of DIMMs per channel, as shown under "Maximum operating speed" in Table 5.

The following memory protection technologies are supported:

ECC



Chipkill (for x4-based memory DIMMs)



Chipkill works only in independent channel mode (the default is operational mode) and supports only

x4-based memory DIMMs.
