Capacity and configuration

This kit delivers 512GB of DDR4 memory in eight 64GB registered DIMMs. It is built for servers and workstations that require high-density ECC memory for virtualisation, database or AI workloads.

Thermals and power

Each module operates at 1.2V without a heat spreader, relying on chassis airflow for cooling. Registered buffering and ECC operation keep signal integrity stable under sustained load in dense multi-socket platforms.

Platform compatibility

The kit is validated for the ASRock Rack ROMED8-2T motherboard with AMD EPYC processors. Buyers using other server boards or consumer platforms should verify qualified vendor lists before purchase.

Questions about this item

How do I install these 288-pin DDR4 RDIMM modules into the ASRock Rack ROMED8-2T, and what step is commonly missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips lock, then verify all eight 64GB modules are recognised in the BIOS before closing the case.

What maintenance or replacement will this 512GB ECC registered kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only necessary if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What limit appears first when this DDR4 3200 CL22 memory runs sustained workloads on an EPYC platform?

The CL22 latency at 1.20V sets the practical throughput ceiling; sustained heavy loads will hit latency-bound performance before thermal or voltage limits become an issue.
