SK hynix HMA84GR7MFR4N-UH 32G DDR4 2400 RDIMM
The SK hynix HMA84GR7MFR4N-UH is a 32GB DDR4-2400 registered ECC DIMM intended for B2B buyers provisioning or maintaining x86 server platforms — virtualization hosts, storage systems, and general-purpose workloads. As a PC4-19200R RDIMM, it is suited to dual-socket and multi-channel server boards that require registered modules for stable population across all DIMM slots. Note that registered DDR4 modules are platform-dependent: confirm your board and CPU support DDR4 RDIMMs at this data rate before ordering, as RDIMMs cannot be mixed with LRDIMMs or consumer-grade UDIMMs.

Good to know
- RDIMMs require a server/workstation platform with registered-memory support and do not mix with UDIMMs, LRDIMMs, or DDR5 modules in the same channel — verify your motherboard’s qualified vendor list (QVL) before ordering.
- Within the DDR4 server memory family, DDR4-2400 with CL17 sits at the entry point of the DDR4 performance range; x4 dual-rank organization offers a good balance of density and reliability for virtualization hosts and cache-tier workloads.
- For multi-socket builds, populate DIMM slots evenly across channels per your server vendor’s population guide; ordering modules in matched sets of the same model, rank, and data rate helps avoid training issues at boot.
