NEMIX RAM 8GB DDR4 2933 CL21 ECC RDIMM ASRock Rack ROMED8-2T

SKU CH-E436-XAH0E

8GB DDR4 2933 CL21 ECC registered RDIMM for ASRock Rack ROMED8-2T EPYC servers

  • Capacity8GB
  • SpeedDDR4 2933 (PC4 23400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V

Capacity 8GB

  • ECC protection prevents data errors in critical workloads
  • Registered design stabilises signals for dense server configurations
  • 2933 MT/s throughput matches EPYC platform specifications
  • 2 V operation reduces power draw per module
  • 288-pin RDIMM form factor fits ASRock Rack ROMED8-2T slots

Server-grade ECC RDIMM for EPYC platforms

This 8 GB DDR4 module is built for the ASRock Rack ROMED8-2T motherboard and AMD EPYC processors. Registered operation and ECC support protect data integrity in multi-socket server workloads. The single-rank 1Rx8 organisation keeps electrical loading low per channel.

288-pin DDR4 slot at 1.2 V

Installation requires a compatible 288-pin DDR4 RDIMM slot running at 1.20 V. Registered buffering removes address and command loading from the memory controller, freeing electrical headroom for higher DIMM counts per channel. No heat spreader is fitted, so airflow across the module must be provided by the chassis.

8 GB at 2933 MT/s with CL21

The module delivers 8 GB of capacity at 2933 MT/s (PC4-23400) with a CAS latency of 21 cycles. This density suits moderate virtualization, database caching or file-serving tasks where error correction matters more than raw bandwidth. Workloads needing larger per-DIMM capacities or faster transfer rates will require higher-density or higher-speed registered DIMMs.

Questions about this item

What is the CAS latency of this DDR4 module?

The module runs at CL21, which is the CAS latency specified for this 2933 MT/s DDR4 registered DIMM.

How much power does the 1.2 V registered ECC DIMM draw under continuous load?

Operating at 1.20 V, this registered ECC RDIMM draws minimal power; the register adds slight overhead but total consumption stays low for an 8 GB server module.

Which motherboard must I already have for this memory to work?

This kit is validated for the ASRock Rack ROMED8-2T motherboard designed for AMD EPYC processors.
