The Samsung M321RYGA0BB0-CQK is a 96GB DDR5-4800 ECC registered DIMM (RDIMM) stocked for enterprise server builds, cloud infrastructure rollouts, AI training cluster deployments, and continuous-duty data center environments. It is a natural fit for resellers fulfilling DDR5-generation server refresh projects and for system integrators standardizing on registered ECC memory across virtualization hosts, cache tiers, and compute-heavy workloads. Please note: as a DDR5 RDIMM it is not backward-compatible with DDR4 sockets, and mixing different generations or module types on the same platform is not supported.

Supply & Sourcing Overview
We maintain this part number in active inventory with stock levels verified before order confirmation. Orders shipped from the same warehouse batch carry consistent date codes and identical firmware/revision markings, which simplifies lot tracking, deployment audits, and downstream warranty management for resellers and integrators managing multi-node rollouts.
All units are original manufacturer stock backed by our standard wholesale warranty policy. RMA requests are processed through a dedicated B2B channel with defined turnaround targets, and replacement or credit options are available depending on the agreement tier. Every shipment is export-ready and complies with CE, FCC, and RoHS requirements, with documentation available on request for customs and tender submissions.
Lead times depend on order volume and current allocation status. Standard in-stock quantities typically ship within short order processing windows; larger project volumes can be reserved via scheduled delivery plans. For mixed-capacity builds, integrators should confirm memory population rules with the server vendor to keep all channels running at the rated 4800 MT/s.
Whether you are building out high-density virtualization hosts or standardizing a 96GB-per-slot memory baseline across a fleet, we support procurement with flexible order sizes and batch consistency guarantees. For current allocation, pricing tiers, and stock confirmation, request a wholesale quote and our sourcing team will respond with a formal offer.
