SK hynix HMA84GR7DJR4N-XN 32G DDR4 3200 RDIMM
The SK hynix HMA84GR7DJR4N-XN is a 32GB DDR4 ECC registered DIMM (RDIMM) rated at 3200 MT/s (PC4-25600R), aimed at enterprises and resellers provisioning or maintaining server fleets. It suits virtualization hosts, database servers, and storage/cache-tier deployments where registered memory with error correction is required. Note that as a DDR4 RDIMM, it is only compatible with DDR4 server platforms supporting registered modules — it cannot be mixed with DDR5 memory or used in desktop-class boards.

Good to know
- Compatibility: requires a server platform with DDR4 registered memory support; do not mix with DDR5 modules, UDIMMs, or LRDIMMs in the same channel. Actual operating speed may be lower depending on the installed CPU and memory configuration.
- Family positioning: within SK hynix’s DDR4 RDIMM lineup, this dual-rank (2Rx4) 32GB module balances capacity per DIMM slot with stable signal behavior, and supports balanced channel population (e.g., filling channels evenly) for optimal bandwidth in multi-socket servers.
- Buying tip: verify your server’s qualified memory list (QVL) or OEM part-equivalence before ordering, and match rank configuration and speed grade across existing modules to avoid downclocking or population limits.
