The SK hynix HMA82GR7DJR4N-XN is a 16GB DDR4-3200 ECC registered DIMM (RDIMM) sourced for volume distribution to resellers, system integrators, and IT procurement teams building out enterprise servers, data centers, virtualization clusters, and storage platforms. As a JEDEC-standard registered module with ECC, it is a high-turnover SKU for server memory lines and fits build-to-order configurations for high-availability workloads. Buyers should confirm that target server platforms support DDR4 registered modules at the 3200 MT/s speed grade at the intended population before placing volume orders.
Supply & Batch Consistency
Stock is maintained in allocation-ready quantities, and we ship from a single batch wherever possible so that integrators deploying multiple units into the same server or rack receive matched modules with consistent die revision and firmware. When ordering for multi-server rollouts, indicate your batch-consistency requirement at inquiry stage and we will confirm available lot codes prior to shipment.
Quality, Warranty & Compliance
All modules are original SK hynix product, fully traceable, and covered by our wholesale warranty with a defined RMA process for DOA and failure claims. The product carries CE, FCC, and RoHS certification documentation, and export paperwork can be provided to support customs clearance in destination markets. Every shipment is ESD-packed and inspected before dispatch.

Technical Guidance for Integrators
- DDR4 RDIMMs are platform-specific: they will not operate in DDR5 or LRDIMM-only slots, and must not be mixed with unbuffered or load-reduced modules in the same channel. We recommend validating against the motherboard QVL and per-CPU supported speed grades before committing to a purchase order.
- The 2Rx4 dual-rank x4 organization provides a practical balance of density and signal integrity; PC4-25600R (3200 MT/s, CL22) is a mainstream baseline for current DDR4 server platforms, though effective data rate depends on the CPU memory controller and channel population.
- For stable channel population and predictable performance across a deployment, populate all channels with identical model, capacity, and rank configuration — specify consistent batch/die revision when ordering multiple units per server.
