NEMIX RAM 512GB 8x64GB DDR5-4800 CL40 1.1V 2Rx4 ECC RDIMM Supermicro H13SSF

Exact-fit DDR5 kit for Supermicro H13SSF

This 512GB kit contains eight 64GB DDR5-4800 RDIMMs built to the board's native speed and timing. Registered ECC modules with 2Rx4 organization and 1.10V operation match the memory controller's expectations so the full capacity is recognized immediately. It targets administrators who need maximum registered memory on this specific platform without manual tuning.

Build integration with registered DDR5

The 288-pin RDIMM form factor is the only type the H13SSF accepts; UDIMMs or SODIMMs will not seat or function. Registered buffering reduces electrical load on the controller, allowing all eight slots to run fully populated at the rated 4800 MT/s. ECC corrects single-bit errors in flight, protecting data integrity in continuous workloads. No heat spreaders are fitted, so airflow across the DIMM rows must be maintained by the chassis.

Capacity ceiling and headroom

Eight ranks per module across eight DIMMs deliver 512GB total, the maximum this kit provides. CL40 latency and 1.10V are fixed at the JEDEC DDR5-4800 specification; there is no XMP or higher-speed profile to enable. Workloads that exceed 512GB or require faster transfer rates will need a different platform, as this kit cannot be expanded or overclocked beyond its validated configuration.
