SK hynix HMA84GR7MFR4N-TF 32G DDR4 2133 RDIMM
The SK hynix HMA84GR7MFR4N-TF is a 32GB DDR4-2133 registered ECC DIMM aimed at enterprise buyers maintaining or expanding older-generation server fleets — virtualization hosts, storage controllers and 24/7 data center platforms that still run on DDR4. As an RDIMM, it offloads addressing to a register, allowing higher module counts per channel than unbuffered memory; note that RDIMMs cannot be mixed with LR-DIMMs or consumer UDIMMs in the same platform. Verify your board’s supported DDR4 speed and population rules before ordering, as effective bandwidth depends on the platform memory controller.

Good to know
- This is a registered ECC module: it will only work in server/workstation boards supporting RDIMMs and will not function in desktop platforms, nor alongside DDR3 or DDR5 modules of any type.
- Within SK hynix’s DDR4 RDIMM line, this 2133 MT/s dual-rank module sits in the entry speed tier of the DDR4 family — a common fit for earlier-generation Intel/AMD server platforms whose memory controllers top out at this rate.
- Buying tip: for consistent multi-channel operation, populate channels with matched modules (same part number, rank and speed) and follow your server vendor’s slot population order for optimal performance.
