256GB DDR4 ECC RDIMM Kit for ASRock EPYC Servers

This 256GB kit contains eight 32GB DDR4 2666 registered DIMMs built with ECC for data integrity. It is designed for ASRock Rack ROMED8-2T motherboards running AMD EPYC processors in server and workstation roles.

Sustained Load Behaviour

Modules are stress tested under load to maintain stability during continuous operation. The registered design and 1.2V operation help keep signal quality consistent across all eight slots during extended workloads.

2Rx4 Organisation Decides Fit

Each module uses a 2Rx4 rank configuration that must match the motherboard memory topology. Verify the platform supports this rank structure before purchase; systems requiring a different organisation will not accept the kit.

Questions sur cet article

How much power does the 256GB DDR4 2666 kit draw when running continuously at 1.2V?

Each 32GB module operates at 1.20V, so the eight-module kit runs at standard DDR4 voltage with no extra power overhead.

What motherboard slot and CPU memory controller are required for these 288-pin ECC RDIMMs?

You need a DDR4 RDIMM-capable motherboard such as the ASRock Rack ROMED8-2T with an AMD EPYC processor that supports registered ECC memory.

Will the 2Rx4 registered modules work alongside older single-rank unbuffered DDR4 DIMMs?

No, registered 2Rx4 RDIMMs cannot be mixed with unbuffered UDIMMs; the memory controller requires all slots to use the same registered ECC type.
