Description
NEMIX RAM memory upgrades for the Lenovo ThinkSystem SR650 V2 Rack Server: DDR4-3200 ECC Registered (RDIMM) modules from 16GB to 128GB, sold as single modules and matched kits of up to 16, selected as drop-in, compatibility-tested replacements. 1.2V, 288-pin, JEDEC-compliant. This system runs one or two 3rd Gen Intel Xeon Scalable processors with 32 DDR4 DIMM slots (16 per processor, eight channels with two DIMMs per channel), supporting up to 8TB of memory with 256GB 3DS RDIMMs. Lenovo rates the platform at DDR4-3200, including at two DIMMs per channel. Lenovo positions the ThinkSystem SR650 V2 as a 2U, two-socket rack server for storage-rich virtualization, databases, analytics and AI 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.
