  • Dual-rank 2Rx4 organisation maximises density per DIMM slot
  • 2 V operation reduces power draw in dense configurations

ASRock Rack ROMED8-2T compatible DDR4 ECC RDIMM kit

This 64GB kit contains two 32GB registered DDR4 modules built for the ASRock Rack ROMED8-2T motherboard. ECC and registered operation protect data integrity in server and workstation workloads. The modules run at 2933MHz with CL21 latency at 1.2V. No heat spreaders are fitted.

Sustained load stability on EPYC platforms

All modules are stress tested under load to verify reliability during continuous operation. Registered buffering reduces electrical load on the memory controller, helping maintain consistent throughput in multi-threaded server tasks. ECC corrects single-bit errors without halting the system. The 2Rx4 organisation supports high-density population on compatible boards.

2Rx4 rank density decides slot population

Each 32GB module uses a 2Rx4 configuration, which determines how many kits can be installed per channel on the target motherboard. Builders needing different rank density or non-ECC unbuffered memory cannot use this kit. Verify the platform's qualified vendor list for maximum supported capacity per slot.

Questions about this item

How much power does the 1.2V DDR4 2933MHz ECC RDIMM kit draw under continuous load?

Each module operates at 1.2V; total draw depends on the server platform and workload, but registered ECC DDR4 at this voltage is designed for efficient 24/7 operation in EPYC systems.

What motherboard slot and chipset support are required to run this 2Rx4 registered kit?

You need a motherboard with 288-pin DDR4 RDIMM slots that supports registered ECC memory, such as the ASRock Rack ROMED8-2T for AMD EPYC processors.

Will this CL21 2Rx4 registered kit work alongside older single-rank DDR4 ECC modules?

Mixing ranks and latencies is not recommended; the 2Rx4 organisation and CL21 timing should be matched across all populated channels for stable operation.
