SK hynix HMA82GR7DJR4N-XN 16G DDR4 3200 RDIMM
The SK hynix HMA82GR7DJR4N-XN is a 16GB DDR4-3200 ECC registered DIMM (RDIMM) built for enterprise servers, data centers, cloud platforms, virtualization hosts, and storage systems. It targets IT buyers and system integrators who need JEDEC-standard registered memory with ECC for reliable, high-availability workloads. Note that as a DDR4 RDIMM, it must be paired with a server platform that explicitly supports DDR4 registered modules and the 3200 MT/s speed grade at the intended population.

Good to know
- DDR4 RDIMMs are not backward or forward compatible: they will not operate in DDR5 or LRDIMM-only slots, and should not be mixed with unbuffered or load-reduced modules in the same channel. Always verify your motherboard’s QVL and supported speed grades per CPU generation before ordering.
- Within the DDR4 RDIMM family, the 2Rx4 dual-rank x4 organization offers a balance of density and signal integrity; the PC4-25600R speed grade (3200 MT/s, CL22) is a common baseline for modern DDR4 server platforms, though actual data rate may be downclocked depending on CPU memory controller and channel population.
- Buying tip: for stable channel population and best performance, install matched modules of the same model, capacity, and rank configuration across all channels — request consistent batch/die revision when ordering multiple units for the same server.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
