512 GB DDR5 ECC RDIMM kit

This 512 GB kit contains four 128 GB DDR5 4800 ECC registered DIMMs built for Supermicro servers and workstations. It targets IT teams and system builders who need maximum registered memory capacity for virtualization, database or compute workloads.

Check motherboard RDIMM support and slot count

Verify that your Supermicro platform accepts 288-pin DDR5 RDIMMs and has at least four available slots. The modules run at 1.1 V with CL40 latency and a 4Rx4 organisation, so the memory controller must support registered ECC operation at DDR5 4800 speeds.

Four-module kit enables full population

The package delivers four matched 128 GB sticks, allowing you to populate a full bank or complete a quad-channel configuration in one order. No heat spreaders are included, so ensure your chassis airflow meets the server vendor's thermal guidelines for dense memory layouts.
