Memory
Lenovo DDR4 memory is compatibility tested and tuned for optimal ThinkServer performance and
throughput. From a service and support standpoint, Lenovo memory automatically assumes the system
warranty, and Lenovo provides service and support worldwide.
The RD550 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 RD550 supports up to 768 GB of memory at up to 1866 MHz when fully populated. The actual
memory speed in the system is determined as the lowest of the memory speed that is supported by the
specific CPU or the maximum operating speeds for the memory configuration that is based on the number
of DIMMs per channel.
ThinkServer engineering tested and validated system designs that support memory speeds beyond Intel's
original plan, which provides benefits for workloads that require memory speed and density. Lenovo
ThinkServer memory is fully supported up to the rated speeds that are shown in the following table.

DIMMs per channel
Memory bus speed
1 DPC 2133 MHz
2 DPC 2133 MHz
3 DPC 1600 MHz
The following rules apply when the memory configuration is selected:
The server supports RDIMMs and LRDIMMs.
Mixing different types of memory (RDIMMs and LRDIMMs) is not supported.
DIMM capacities and rank can be mixed.
