The SK hynix HMA84GR7DJR4N-XN is a 32GB DDR4 ECC registered DIMM (RDIMM) rated at 3200 MT/s (PC4-25600R), offered through our TO-B channel for resellers, system integrators and IT procurement teams provisioning or maintaining server fleets. Typical deployment scenarios include virtualization hosts, database servers, and storage/cache-tier systems that require registered memory with error correction. As a DDR4 RDIMM, it is compatible only with DDR4 server platforms supporting registered modules — it cannot be combined with DDR5 memory or installed in desktop-class boards.
We maintain stable, recurring stock of this SK hynix original part. Modules are supplied in consistent production batches, which is critical for integrators building multi-socket servers where mixed DRAM die revisions can cause population issues or subtle instability. When you place a repeat order, we make every effort to match the batch code of your previous shipment — simply note this requirement on your inquiry.
All units are genuine SK hynix products backed by our wholesale warranty policy. RMA requests are handled through a dedicated B2B channel with defined turnaround targets, so failed modules in deployed fleets can be replaced without prolonged downtime for your customers. Every shipment includes export-ready documentation, and the product carries CE, FCC and RoHS compliance for delivery into most international markets. We can advise on destination-specific requirements during the quotation stage.

Good to know
- Platform requirements: the host server must support DDR4 registered memory; do not mix DDR5 modules, UDIMMs, or LRDIMMs in the same channel. Achieved operating speed may be lower depending on the installed CPU and memory configuration.
- Positioning within the lineup: in SK hynix’s DDR4 RDIMM range, this dual-rank (2Rx4) 32GB module offers a strong balance of per-slot capacity and signal stability, and supports balanced channel population for optimal bandwidth in multi-socket deployments.
- Pre-order validation: we recommend that procurement teams confirm the server’s qualified memory list (QVL) or OEM part-equivalence before ordering, and keep rank configuration and speed grade consistent across existing modules to avoid downclocking or population limits. Our sales engineers can assist with cross-referencing part numbers.
For volume buyers, standard configurations ship from ready inventory, while large project orders are scheduled against confirmed batch allocation. To receive batch-consistency guarantees, volume pricing and current stock confirmation, request a wholesale quote and our team will respond with a tailored offer.
