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.

Questions about this item

What DDR5 speed and PC5 rating does this 576GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 data rate, matching the Supermicro H14SHM memory controller specification.

What physical slot and form factor do these 48GB modules require?

Each module uses a 288-pin DDR5 RDIMM form factor; the board must provide 12 registered DIMM slots to accept the full kit.

In what order should the 12 RDIMMs be populated on the H14SHM?

Follow the motherboard manual's approved DIMM population sequence for 12 modules to ensure all 576GB are recognised at rated speed.
