Server Memory Upgrade

This 16GB DDR4 module is built for the ASRock Rack ROMED8-2T motherboard supporting AMD EPYC processors. It delivers registered ECC reliability at 3200MHz with a CL22 latency. The single 288-pin RDIMM uses 2Rx8 organisation and runs at 1.2V. It is designed to expand server memory capacity with enterprise-grade stability.

Compatibility Constraints

Suitable for administrators upgrading the specified ASRock Rack platform where registered ECC DDR4 is required. Not suitable for systems that accept only unbuffered non-ECC UDIMMs or that lack support for registered modules. Buyers needing higher densities per slot or different form factors must verify motherboard qualification lists before purchase.

Decisive Specification

The registered ECC RDIMM format is the single attribute that determines fit. Only motherboards qualified for DDR4 288-pin registered memory with ECC can use this module. Confirm the ROMED8-2T memory QVL matches this part number before ordering.

Questions about this item

How does the 2Rx8 rank configuration affect sustained throughput on the ASRock Rack ROMED8-2T?

The dual-rank 2Rx8 organisation allows the memory controller to interleave accesses across two ranks per channel, improving bandwidth utilisation during long-running workloads on the EPYC platform.

What thermal behaviour should I expect from the 1.2 V DDR4 modules when the server runs continuously?

Operating at 1.2 V without a heat spreader, the RDIMMs rely on chassis airflow across the 288-pin slots; registered buffering reduces electrical load, keeping temperatures within normal server limits.

Which motherboard feature must be present for this ECC RDIMM to function?

The ASRock Rack ROMED8-2T must provide registered DIMM slots with ECC support for the DDR4 3200 CL22 modules to operate correctly.
