The SK hynix HMA82GR7DJR8N-XN is a 16GB DDR4-3200 ECC registered DIMM targeted at B2B buyers who need dependable registered DDR4 in volume — including IT resellers, system integrators, and corporate procurement teams building virtualization hosts, cloud compute nodes, and enterprise storage platforms. Supplied as a PC4-25600R module, it is compatible only with server platforms that support DDR4 RDIMM; it cannot operate alongside DDR5 memory, and channel population must follow the memory population rules of the target motherboard or qualified memory list (QVL).
For channel stocking, we maintain steady availability of this SKU and can ship from consistent, single-batch inventory so that multi-unit deployments receive modules with matching model, rank, and speed grade — a key requirement for stable multi-channel server builds and for resellers who need batch consistency across repeat orders.
All units ship with our standard B2B warranty and RMA handling: DOA units and warranty claims are processed through a dedicated channel with defined turnaround windows, so resellers can pass warranty confidence on to their own customers. Goods are CE, FCC, and RoHS compliant and are documented for export, supporting cross-border procurement and integration into EU/US-bound system builds.

Integration & Deployment Notes
- Mixing rules: registered DDR4 RDIMMs cannot be combined with UDIMMs, LRDIMMs, or DDR5 modules on the same platform. Integrators should validate against the server vendor’s QVL before committing to volume orders.
- Workload fit: the dual-rank 2Rx8 layout provides effective interleaving for virtualization and cache-tier workloads; note that dual-rank modules may reduce maximum per-channel population on some platforms.
- Batch sourcing: for multi-module builds, we recommend ordering all modules for a given project from one batch; our stocking model supports matched-batch fulfillment to keep timings consistent across channels.
