Description
NEMIX RAM memory upgrades for the Lenovo ThinkSystem SR950 Mission-Critical Server: DDR4-2933 ECC Registered (RDIMM) modules from 16GB to 128GB, 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 two to eight 1st or 2nd Gen Intel Xeon Scalable processors with 96 DDR4 DIMM slots (12 per processor), supporting up to 12TB with 128GB modules and up to 24TB with 256GB 3DS RDIMMs on processors that address it. 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 and 128GB modules require 2nd Gen processors. Lenovo positions the ThinkSystem SR950 as a 4U, scalable two- to eight-socket server for the largest in-memory databases and mission-critical workloads. 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.
