NEMIX RAM 16GB DDR5 ECC RDIMM for ThinkEdge SE455 V3

This registered DDR5 module adds 16GB of error-correcting memory to the Lenovo ThinkEdge SE455 V3 AI server. It runs at 5600MHz with CL46 latency and operates at 1.1V. The 1Rx8 organisation uses a single rank of eight-bit chips on a 288-pin RDIMM form factor.

Capacity and headroom at 5600MHz CL46

A single 16GB stick expands the server's registered memory pool for inference workloads and virtualised services that benefit from ECC protection. The registered buffer reduces electrical load on the memory controller, allowing larger total capacities than unbuffered modules. Workloads that exceed 16GB per channel will require additional RDIMM modules to scale further.

Package content and installation

The package contains one 16GB DDR5 5600MHz PC5-44800 1Rx8 1.1V CL46 288-pin ECC RDIMM module. No heat spreader is fitted, so airflow across the chips relies on the server's internal cooling design. Installation follows the standard RDIMM procedure outlined in the ThinkEdge SE455 V3 service manual.

Questions about this item

Will the 5600MHz DDR5 module work with other DDR5 RDIMMs already installed in my ThinkEdge SE455 V3?

Yes, the module follows JEDEC DDR5 5600MHz PC5-44800 1Rx8 1.1V CL46 288-pin ECC RDIMM specifications, so it will operate alongside identical-spec DDR5 RDIMMs in the server.

How can I confirm the 16GB ECC RDIMM is running at 5600MHz CL46 after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 5600MT/s, CL46, 1.1V, ECC registered, 1Rx8 organisation for the new module.

Does the package include only the 16GB DDR5 5600MHz ECC RDIMM or are extra parts supplied?

The box contains one 16GB 288-pin DDR5 5600MHz PC5-44800 1Rx8 1.1V CL46 ECC RDIMM; no heat spreader, cables or additional hardware are included.
