2X16GB DDR4-3200 ECC RDIMM Compatible with Lenovo ThinkSystem ST650 V2 | PC4-25600 2Rx8 1.2V CL22 288-PIN Registered ECC Server Memory, 32GB Kit of 2. Fits Lenovo ThinkSystem ST650 V2.

EXACT-MATCH UPGRADE — 32GB kit (2 x 16GB) DDR4-3200 (PC4-25600), 2Rx8 Registered ECC, 1.2V, CL22, 288-pin. Matched set from a single production lot — the precise rank, voltage, and timing your system's memory controller expects, recognized at full capacity and rated speed.

VERIFIED FITMENT — Compatible with the Lenovo ThinkSystem ST650 V2 Tower Server. The 288-pin Registered (RDIMM) form factor this server requires — not a UDIMM, LRDIMM or SODIMM. Spec-matched to the server's memory-population rules.

ENTERPRISE STABILITY — Registered (buffered) architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly — stopping silent data corruption and unplanned reboots before they reach production.

CHECK YOUR CONFIG — Server and motherboard memory support varies by model and processor. Consult your system manual for supported capacities, approved DIMM population order, and installation steps before purchase.

LIFETIME SUPPORT — Backed by a lifetime replacement warranty and free US-based technical support. Researched, matched, and compatibility-tested by NEMIX RAM, a US-based server memory specialist since 1993, and backed by a lifetime warranty.
