Compatible DDR4 RDIMM for ASRock EPYC systems

This registered ECC module is built for ASRock Rack ROMED8-2T motherboards running AMD EPYC processors. It targets server and workstation builders who need validated memory for mission-critical workloads. The single 64 GB stick simplifies population of available DIMM slots.

Registered ECC with 2Rx4 organisation

The module operates as a registered dual-rank x4 device, delivering error correction and signal buffering required by multi-socket server platforms. CL19 latency at DDR4 2666 ensures compatibility with the platform’s memory controller without overclocking. Voltage is set at the standard 1.20 V for DDR4 server memory.

64 GB capacity per module

One stick provides 64 GB of addressable memory, allowing high-density configurations when multiple slots are filled. Workloads such as virtualisation, database caching and large-scale analytics benefit from the added headroom. Systems requiring more than the per-module limit must populate additional slots with identical registered ECC parts.

Soalan tentang produk ini

How does the 2666 MT/s speed translate once the module is installed in a compatible ASRock EPYC motherboard?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency and 1.20 V, delivering the rated throughput on supported EPYC platforms.

What does the ECC RDIMM registered interface mean for system stability and maximum capacity?

Registered ECC adds error correction and a register buffer, allowing the memory controller to drive higher capacities reliably on server boards.

Will the 288-pin 2Rx4 stick fit the DIMM slots on an ASRock Rack ROMED8-2T without a heat spreader?

Yes — it is a standard 288-pin DDR4 RDIMM with no heat spreader, so it seats directly in the board's DDR4 slots.
