64GB DDR4-3200 ECC RDIMM Compatible with Synology D4ER01-64G

Key features

• EXACT-MATCH UPGRADE — 64GB DDR4-3200 (PC4-25600), 2Rx4 Registered ECC, 1.2V, CL22, 288-pin. The precise rank, voltage, and timing your system's memory controller expects, so it is recognized at full capacity and runs at its rated speed.
• VERIFIED FITMENT — Drop-in replacement for Synology D4ER01-64G and D4ER02-64G. For Synology SA6400, FS6420, RS11626xs+, PAS7700. The 288-pin Registered (RDIMM) form factor these systems require — not a UDIMM, LRDIMM or SODIMM. Spec-matched to Synology'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.
