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

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.
