SK hynix HMA82GR7CJR8N-XN 16G DDR4 3200 RDIMM
The SK hynix HMA82GR7CJR8N-XN is a 16GB DDR4 ECC Registered DIMM (RDIMM) rated at 3200 MT/s (PC4-25600R), built to JEDEC DDR4 standard for enterprise servers, data centers, virtualization platforms, storage servers, and cloud computing systems. With ECC support and a dual-rank 2Rx8 configuration, it is a practical fit for virtualization hosts and cache-tier deployments where data integrity and stable sustained bandwidth matter. As an RDIMM, it must be matched to platforms that specifically support registered DDR4 — it cannot be mixed with DDR5 modules or used in desktop/consumer UDIMM slots.
Key specifications (table)
| Parameter | Specification |
|---|---|

Good to know
- Compatibility: This is a registered DDR4 module for server/workstation boards with RDIMM support — verify your platform’s qualified vendor list (QVL) and BIOS support for DDR4-3200; it will not function in UDIMM-only or DDR5 systems.
- Within the SK hynix DDR4 RDIMM family, this 16GB dual-rank (2Rx8) module sits in the mainstream capacity tier — pairing identical modules across all supported channels is the standard practice for maximizing bandwidth on dual-socket servers.
- Buying tip: For mixed fleet expansion, keep rank configuration and speed grade consistent per channel to avoid the memory bus downclocking to the slowest module.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
