Green rectangular DDR4 RDIMM module with black memory chips and gold edge connectors

SK hynix

SK hynix HMA81GR7CJR8N-XN 8GB DDR4-3200 ECC RDIMM 1Rx8

SKU CH-QM6E-CB3H8

8GB DDR4-3200 ECC RDIMM 1Rx8 server memory for error-corrected stability

  • ECC protection prevents data corruption in servers
  • DDR4-3200 speed delivers 25600 MB/s bandwidth
  • 2 V operation reduces power consumption
  • Standard-height RDIMM fits typical server slots
  • Single-rank 1Rx8 layout supports dense configurations

Server RDIMM for ECC workloads

This SK hynix module is an 8GB DDR4-3200 registered DIMM with ECC and a 1Rx8 organisation. It operates at 1.2V and conforms to the standard RDIMM height. The single-stick kit targets servers and workstations that require error-correcting memory for data integrity.

Sustained throughput at PC4-25600R

Rated at PC4-25600R, the module maintains its 3200 MT/s transfer rate under continuous load rather than only in short bursts. The registered buffer helps stabilise the command and address signals across multiple ranks in dense configurations. ECC correction runs continuously without halting the data path during normal operation.

Verify RDIMM slots and voltage

Confirm the motherboard accepts DDR4 RDIMMs and supports 1.2V operation before ordering. Systems limited to UDIMMs or to higher-voltage modules will not post with this stick. The single 8GB capacity may also limit total memory if the platform has few populated slots.

Points forts

  • DDR4-3200 speed delivers 25600 MB/s bandwidth
  • 2 V operation reduces power consumption
  • Standard-height RDIMM fits typical server slots
  • Single-rank 1Rx8 layout supports dense configurations

Questions sur cet article

How much power does the 1.2 V DDR4-3200 RDIMM draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.2 V; actual power draw depends on the platform's memory controller and workload.

What motherboard features are required for this ECC RDIMM to function?

A server-class motherboard with DDR4 RDIMM slots that support ECC and the PC4-25600R data rate is needed.

Can this 1Rx8 8 GB stick be mixed with older DDR4 RDIMMs of different ranks or speeds?

Mixing ranks or speeds is possible only if the platform's memory controller and BIOS allow it; the module itself is a single-rank 1Rx8 device at 3200 MT/s.
