Lenovo ThinkEdge SE455 V3 compatible DDR5 ECC

This 64 GB kit contains two 32 GB DDR5 registered DIMMs built for the Lenovo ThinkEdge SE455 V3 AI server. Each module runs at 5600 MT/s with CL46 latency and operates at 1.1 V. The registered design and on-die ECC protect data integrity in continuous workloads.

Registered ECC RDIMM with 2Rx4 organisation

The modules use a 2Rx4 rank layout and 288-pin DDR5 RDIMM form factor, so they install only in platforms that accept registered ECC memory. Buffered signalling reduces electrical load on the memory controller, allowing the full 64 GB capacity to be populated without signal degradation. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this kit.

Two matched modules enable dual-channel population

The pair is packaged together so both channels can be filled identically, giving the memory controller balanced ranks for optimal throughput. No heat spreaders are included, relying on server airflow for cooling. The kit contains only the two DIMMs; no additional cables, software or documentation are bundled.

Questions about this item

What does the DDR5 5600 speed deliver once installed in the ThinkEdge SE455 V3?

The kit runs at 5600 MT/s with CL46 latency, providing the maximum standard data rate the platform supports for registered ECC memory.

How does the 288-pin RDIMM interface and registered design affect usable capacity?

The 288-pin DDR5 RDIMM format with 2Rx4 organisation and on-board register enables full 64 GB capacity while maintaining signal integrity on the server memory bus.

What physical clearance does the 2 x 32 GB kit require inside the chassis?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so it fits the ThinkEdge SE455 V3 DIMM slots without extra vertical clearance.
