The SK hynix HMA82GR7CJR8N-XN is a 16GB DDR4 ECC Registered DIMM (RDIMM) rated at 3200 MT/s (PC4-25600R), manufactured to the JEDEC DDR4 specification for enterprise servers, data centers, virtualization platforms, storage servers, and cloud computing infrastructure. Supplied with ECC support and a dual-rank 2Rx8 configuration, it is a dependable choice for system integrators building virtualization hosts and cache-tier nodes where sustained bandwidth and data integrity are required. As a registered module, it must be deployed only in platforms that support RDIMM — it is not compatible with DDR5 slots or desktop/consumer UDIMM boards.

Procurement Guidance
- Batch consistency: Orders are fulfilled from single-date-code lots wherever stock allows, so resellers and integrators receive uniform modules within a purchase batch — essential for channel-matched server builds and clean inventory turnover.
- Compatibility: This is a registered DDR4 module for server and workstation boards with RDIMM support. Confirm your platform’s qualified vendor list (QVL) and BIOS support for DDR4-3200; the module will not operate in UDIMM-only or DDR5 systems.
- Fleet standardization: Within the SK hynix DDR4 RDIMM family, this 16GB dual-rank (2Rx8) part occupies the mainstream capacity tier. Matching identical modules across all supported channels remains best practice for maximizing bandwidth on dual-socket servers.
- Mixed-fleet rollouts: Maintain consistent rank configuration and speed grade per channel when extending existing deployments, preventing the memory bus from downclocking to the slowest installed module.
- Warranty & RMA: All units ship with full manufacturer warranty coverage handled through our channel RMA process, with transparent defect reporting and replacement turnaround for B2B accounts.
- Export compliance: Shipments conform to CE, FCC, and RoHS requirements, with documentation available on request for customs clearance and tender submissions.
