Lenovo ThinkSystem SR665 Rack Server - DDR4 3200MHz PC4-25600 - RDIMM

NEMIX RAM memory upgrades for the Lenovo ThinkSystem SR665 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 AMD EPYC 7002 or 7003 Series processors with 32 DDR4 DIMM slots (16 per processor), supporting up to 8TB of memory with 256GB 3DS RDIMMs. Lenovo rates the platform at DDR4-3200 with one DIMM per channel; standard RDIMMs run at DDR4-2933 with two DIMMs per channel. Lenovo positions the ThinkSystem SR665 as a 2U, two-socket AMD EPYC rack server for storage-rich virtualization, analytics and GPU-accelerated AI. 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.
