Exact-match DDR5-4800 RDIMM kit

This 768GB kit contains sixteen 48GB DDR5-4800 Registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation that matches the board's memory controller requirements. The Registered architecture offloads the controller so every slot runs fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption.

Verified 288-pin form factor

The 288-pin RDIMM form factor fits only boards that accept Registered DDR5 modules; UDIMM or SODIMM slots will not work. Installation follows the motherboard manual's approved population order, which must be checked before purchase because supported capacities and slot sequences vary by model. No heat spreaders are fitted, so airflow must follow the chassis design. The kit is covered by a lifetime replacement warranty and free US-based technical support.

DDR5-4800 bandwidth ceiling

DDR5-4800 (PC5-38400) sets the maximum transfer rate; workloads that demand higher memory bandwidth will hit this limit. Registered buffering adds a small latency overhead versus unbuffered modules, which can affect latency-sensitive tasks. Total capacity is fixed at 768GB across sixteen slots; buyers who need more storage-class memory or a different DIMM type must choose another platform.
