Lenovo ThinkEdge SE455i V3 memory kit

This NEMIX RAM kit adds 64 GB of DDR5 5600 ECC registered memory to the Lenovo ThinkEdge SE455i V3 inferencing server. The kit contains two 32 GB 288-pin RDIMMs running at 1.1 V with a CAS latency of CL46. Modules use major OEM chips and are built for server workloads that require error correction.

Suited for ThinkEdge SE455i V3 capacity upgrades

Ideal for administrators expanding the ThinkEdge SE455i V3 with registered ECC modules that match the platform’s DDR5 5600 specification. Not suited for systems that require unbuffered UDIMMs, non-ECC memory, or a different pin count or voltage.

Straightforward DIMM installation

Install by seating each 288-pin RDIMM into the server’s memory slots until the retention clips engage; no heat spreaders are present to interfere with tight spacing. Common issues include mixing registered and unbuffered modules or populating slots in an order the platform firmware does not support.

Questions about this item

Will this 64GB DDR5 5600 ECC RDIMM kit work in a Lenovo ThinkEdge SE455i V3 server?

Yes, the kit is built for the Lenovo ThinkEdge SE455i V3 inferencing server and matches its DDR5 5600 registered ECC requirements.

Can I mix these 2Rx4 CL46 modules with existing DDR5 4800 RDIMMs in the same server?

The server will run all installed memory at the lowest common speed, so 4800 modules would pull the 5600 kit down to 4800 MT/s.

How do I confirm the kit is running at 5600 MT/s with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 5600 MT/s, CL46, 1.10 V and ECC enabled for each 32 GB module.
