16GB DDR4 ECC RDIMM for servers

This 16GB DDR4 2133MHz ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It operates at 1.20V with CL15 latency and uses a 1Rx4 rank configuration on a 288-pin DIMM form factor. The module serves as a direct replacement for the Hynix HMA82GR7MFR4N-TF part.

Capacity and headroom

A single 16GB stick adds substantial memory capacity for virtualisation, database caching or multi-user workloads on compatible platforms. Registered buffering and ECC protect data integrity under sustained load, while the DDR4 2133 speed rating sets the ceiling for throughput. Systems limited to lower memory speeds or unbuffered DIMMs will not be able to use this module.

Registered ECC requirement decides fit

The defining specification is the registered ECC RDIMM design; only motherboards and processors that explicitly support registered DDR4 ECC memory can accept this part. Consumer desktop boards and laptops that require unbuffered non-ECC UDIMMs are incompatible. Verify your system documentation for RDIMM support before ordering.

Questions about this item

Will this 1Rx4 ECC RDIMM run in a server that currently uses 2Rx4 DDR4 2133 modules?

Yes — both are DDR4 2133 ECC RDIMMs at 1.20 V, so the 1Rx4 module will work alongside 2Rx4 sticks as long as the platform accepts mixed-rank configurations.

How can I confirm the module is operating at PC4-17000 with CL15 after installation?

Check the BIOS or a tool such as CPU-Z; it should report 2133 MT/s, CAS latency 15, 1.20 V and ECC registered operation.

Does the package include only the 16 GB 288-pin DIMM or are extra parts supplied?

The box contains a single 16 GB DDR4 288-pin ECC RDIMM; no cables, brackets or additional components are included.
