Server-grade DDR4 ECC RDIMM

This SK hynix HMA41GR7MFR4N-TF module provides 8 GB of registered DDR4 memory rated at 2133 MT/s with a CAS latency of 15. It operates at 1.2 V and uses a 1Rx4 organisation with on-die ECC for data integrity in server and workstation environments. The 288-pin RDIMM form factor is designed exclusively for compatible enterprise platforms.

Verify registered DDR4 slot support

Confirm that your system accepts registered ECC DDR4 RDIMMs and cannot use unbuffered desktop modules. The motherboard or server chassis must support 1.2 V DDR4-2133 operation and provide 288-pin RDIMM slots. Mixing registered and unbuffered DIMMs is not supported and will prevent boot.

Steady throughput under load

Registered buffering reduces electrical load on the memory controller, allowing sustained data rates during continuous multi-threaded workloads. ECC correction handles single-bit errors without interrupting operation, maintaining consistent bandwidth for virtualisation, database or compute tasks over long periods.
