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 TS150 server has four DIMM slots, and it supports DDR4 UDIMMs with ECC memory protection or
without ECC protection. The processor has two memory channels and supports two DIMMs per channel.
The following rules apply when selecting the memory configuration:
The TS150 server supports memory configurations with 1, 2, 3, or 4 UDIMMs.
Mixing ECC and non-ECC UDIMMs is not supported.
The TS150 server supports up to 2133 MHz memory speeds for one DIMM per channel and two
DIMMs per channel configurations, provided that the processors support this memory speed (see the
Processor options table in the Processors section for details).
The following table summarizes memory speeds and capacities that are supported by the TS150 server.
