SK hynix HMAG78EXNRA084N 16G DDR4 3200 RDIMM
The SK hynix HMAG78EXNRA084N is a 16GB DDR4-3200 ECC registered DIMM (RDIMM) built for enterprise servers, data centers, cloud platforms, virtualization hosts, and storage systems. As a PC4-25600R dual-rank module, it suits buyers populating or expanding DDR4-generation platforms where registered memory and error correction are required. Note that RDIMMs must be deployed on DDR4-compatible platforms and cannot be mixed with DDR5 or unbuffered desktop memory.

Good to know
- As a registered ECC module with a 72-bit data path, this RDIMM is intended for server platforms only — verify your motherboard and CPU support DDR4 RDIMMs, since mixing RDIMMs with UDIMMs or LRDIMMs on the same channel is generally not supported.
- Within the DDR4 RDIMM family, the dual-rank 2Rx8 configuration at 3200 MT/s offers a balance of density and performance for mainstream virtualization and storage workloads; check your platform’s memory population guidelines, as speed support can vary by rank count and number of DIMMs per channel.
- For multi-DIMM builds, purchase modules with matching part number, rank configuration, and speed grade to help ensure stable operation across populated channels.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
