Lenovo ThinkSystem SD550 V3 Multi-Node Server - DDR5 5600MHz PC5-44800 - RDIMM

NEMIX RAM memory upgrades for the Lenovo ThinkSystem SD550 V3 Multi-Node Server: DDR5-5600 ECC Registered (RDIMM) modules from 32GB to 128GB, sold as single modules and matched kits of up to 16 per node, selected as drop-in, compatibility-tested replacements. 1.1V, 288-pin, JEDEC-compliant. Each node runs two 5th Gen Intel Xeon Scalable processors with 16 DDR5 DIMM slots (eight per processor, one DIMM per channel), supporting up to 2TB per node with 128GB 3DS RDIMMs. Lenovo rates the node at DDR5-5600. The ThinkSystem SD550 V3 is a two-socket node for the Lenovo D3 chassis, two nodes per 2U, for HPC and dense compute; memory is listed per node. This platform takes registered ECC memory (RDIMM) only; unbuffered UDIMMs will not work. Use one module size and type throughout the server, and populate memory in the matched groups Lenovo specifies for each processor. Researched, matched, and compatibility-tested by NEMIX RAM, a US-based server memory specialist since 1993, and backed by a lifetime warranty.
