512GB DDR5 RDIMM kit for Supermicro H14DSG-OM

This 512GB kit provides sixteen 32GB DDR5 4800 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. It is intended for administrators who need maximum supported capacity in every slot of this specific platform. Builders using other motherboards or consumer desktop systems cannot use these registered DIMMs.

Sustained-load behaviour

Registered buffering offloads the memory controller so all sixteen slots run fully populated at the rated 4800 speed without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable across continuous workloads.

Installation notes

Modules are keyed 288-pin RDIMMs; they only fit DDR5 RDIMM slots and must follow the motherboard's population order for 16 modules. No heat spreaders are present, so airflow across the sticks is required in dense configurations. Verify the system manual for approved DIMM sequence and BIOS settings before installing.
