Green DDR4 server DIMM with gold contacts and black chips

SK hynix

SK hynix HMA41GR7MFR8N-TF 8GB 2Rx8 DDR4-2133P REG ECC server RAM

SKU CH-N83E-8KF3J

Registered ECC DDR4 module running at 2133 MT/s with dual-rank 2Rx8 organisation for server stability

  • Registered ECC design protects data integrity in servers
  • DDR4-2133 speed delivers 17000 MB/s peak bandwidth
  • 2Rx8 organisation provides 16 internal banks for parallel access
  • 2 V operation reduces power draw versus earlier DDR generations
  • On-die termination and write CRC boost signal reliability

8 GB registered ECC DDR4 module

This SK hynix module provides eight gigabytes of registered ECC DDR4 memory for servers and workstations that require error correction and signal buffering. It operates at DDR4-2133 with a PC4-17000 data rate and uses a 2Rx8 organisation. The part is intended for system integrators and IT teams who verify exact part-number compatibility before deployment.

JEDEC DDR4-2133 electrical and timing envelope

The device runs at a nominal 1.2 V supply with a supported range of 1.14 V to 1.26 V, and VPP at 2.5 V (2.375 V to 2.75 V). JEDEC-standard data rates of 1600, 1866 and 2133 MT/s are supported, with 8-bit prefetch, selectable burst length BL8 or BC4, on-die termination, write CRC, DBI for x8, CA parity and an on-board temperature sensor with SPD. Bank grouping provides 16 internal banks with separate tCCD timing for same-group and different-group accesses.

Authentic SK hynix build with standard RDIMM pinout

The module is manufactured by SK hynix, the world’s second-largest memory chipmaker, and is supplied as a genuine 100 % original component. Its 288-pin RDIMM form factor fits industry-standard DDR4 registered DIMM slots, while the register and ECC circuitry add the signal integrity and single-bit error correction required by multi-socket server platforms. Compliance with the RoHS directive confirms restricted-substance adherence. Buyers who need higher capacities, different ranks or non-ECC unbuffered DIMMs must select alternative parts.

Questions sur cet article

Should I choose the 2Rx8 version or a different rank configuration?

This module uses a 2Rx8 organisation, meaning two ranks of eight-bit wide chips. It suits systems that accept dual-rank registered ECC DIMMs.

What does the PC4-17000P-R rating mean for actual throughput?

PC4-17000P-R indicates a peak transfer rate of 17000 MB/s at DDR4-2133 with registered ECC operation.

Does the DDR4-2133 interface limit speed if my platform supports higher rates?

The DIMM runs at up to 2133 MT/s; it will down-clock to 1866 or 1600 MT/s if the memory controller requires it.
