Lenovo ThinkSystem ST550 Tower Server - DDR4 2933MHz PC4-23400 - RDIMM

NEMIX RAM memory upgrades for the Lenovo ThinkSystem ST550 Tower Server: DDR4-2933 ECC Registered (RDIMM) modules from 16GB to 64GB, sold as single modules and matched kits of up to 12, selected as drop-in, compatibility-tested replacements. 1.2V, 288-pin, JEDEC-compliant. This system runs one or two 1st or 2nd Gen Intel Xeon Scalable processors with 12 DDR4 DIMM slots (six per processor, one DIMM per channel), supporting up to 768GB of memory. Lenovo rates the platform at DDR4-2933 with 2nd Gen Intel Xeon Scalable processors; 1st Gen processors, and some lower-tier 2nd Gen models, run memory at up to 2666 MT/s. These DDR4-2933 modules clock down automatically. With 1st Gen processors, Lenovo supports standard RDIMMs up to 32GB; choose the 16GB or 32GB modules, as the 64GB module requires 2nd Gen processors. Lenovo positions the ThinkSystem ST550 as a two-socket tower (or rack-convertible) server for small and mid-size businesses and remote offices. 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.
