Exact-match DDR5 RDIMM kit for Supermicro H14SHM

This 576GB kit delivers twelve 48GB DDR5-4800 registered ECC modules at 1.1V CL40. It is built for administrators who need every slot populated at rated speed on a Supermicro H14SHM motherboard.

Registered 288-pin form factor

The 288-pin RDIMM design matches the board's memory-population rules and is not compatible with UDIMM or SODIMM slots. Registered buffering reduces electrical load on the controller so all twelve modules operate together at full capacity.

Enterprise-grade ECC at 1.1V with no heat spreader

On-die ECC corrects single-bit errors in real time to prevent silent data corruption and unplanned reboots. The low 1.1V operating voltage keeps power draw modest while the bare modules rely on chassis airflow for cooling.
