32GB DDR4 ECC Registered Kit for Lenovo

This 32GB kit contains two 16GB DDR4 registered DIMMs built for the Lenovo ThinkServer TD350. The modules deliver ECC error correction and registered signalling for stable server operation. They run at 1.2V with a CL15 latency profile.

DDR4-2133 CL15 Registered DIMM Specification

The decisive specification is the DDR4 2133MHz registered ECC design with CL15 timing. The TD350 requires registered modules and cannot mix them with load-reduced DIMMs. Memory speed will clock down automatically based on the installed processor and module count.

Two-Module Kit Enables Dual-Channel Population

The package includes two identical 16GB sticks so you can populate a matched pair of slots. This supports dual-channel bandwidth on the TD350 platform. The kit provides a direct upgrade path toward the system maximum of 256GB registered ECC or 512GB load-reduced memory.

Questions about this item

Will the 2133 MHz speed run at full rate in a ThinkServer TD350?

The module is rated at DDR4-2133, but the server will clock it down to the optimal speed for the installed processor and module count.

What does ECC Registered mean for this 288-pin DDR4 kit?

It provides error-correcting code and a register on each DIMM, which the TD350 requires; registered and load-reduced modules cannot be mixed in the same system.

Does the 2×16 GB kit fit the TD350's 288-pin DIMM slots?

Yes, each stick is a 288-pin DDR4 RDIMM designed for the TD350's eight slots per CPU, up to 16 slots with two CPUs.
