Lenovo ThinkEdge SE450 memory kit

This 128GB kit contains two 64GB DDR4 3200 registered ECC RDIMMs built for the Lenovo ThinkEdge SE450 edge AI server. Each module runs at 1.2V with CL22 latency and a 2Rx4 organisation. The 288-pin form factor matches the server's DIMM slots exactly.

Buyers needing registered ECC memory for this

The kit suits administrators expanding the ThinkEdge SE450 for inference or virtualization workloads that require error correction and registered signalling. It is not for systems that accept only unbuffered non-ECC UDIMMs, nor for platforms limited to lower capacities or different pin counts.

Ready-to-install dual-module package

The two matched 64GB sticks arrive as a tested pair, eliminating the need to source individual modules and verify compatibility separately. No heat spreaders are included, so airflow in the server chassis remains unimpeded. No extra software or cables are bundled.

Questions about this item

Will this 128GB DDR4 3200 ECC RDIMM kit work in my Lenovo ThinkEdge SE450?

Yes, the kit is built for the ThinkEdge SE450 and matches the server's DDR4 3200 registered ECC requirements.

Can I add these two 64GB modules alongside the 32GB RDIMMs already installed in my SE450?

The SE450 supports mixed capacities per channel, so the 2Rx4 64GB modules can run with existing 32GB RDIMMs at the lowest common speed.

How do I confirm the 128GB kit is running at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen — it should show 128GB total, 3200 MT/s, and ECC enabled for each populated slot.
