256GB DDR5 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR5 Registered DIMMs rated at 4800MHz with CL40 latency and 1.1V operation. It is built for servers and workstations that require ECC protection and registered buffering for maximum capacity stability. System administrators populating a Supermicro H14SHM motherboard get the exact rank and timing the platform expects.

288-Pin Registered Form Factor

Each module uses the 288-pin RDIMM layout this board requires, not UDIMM or SODIMM alternatives. Registered architecture reduces electrical load on the memory controller so all eight slots can run fully populated at the rated 4800MHz speed. ECC circuitry corrects single-bit errors on the fly to prevent silent data corruption in production workloads.

1.1V DDR5 Power Efficiency

Operating at the standard DDR5 voltage of 1.1V keeps power draw low across all eight modules during sustained server loads. The absence of heat spreaders relies on chassis airflow for cooling, so adequate case ventilation is necessary. Lower voltage also reduces thermal stress on the memory controller during continuous operation.

Questions about this item

What is the CL40 latency ceiling when all eight DDR5 4800 modules run continuously?

The kit operates at its rated CL40 latency and DDR5 4800 speed when fully populated on the Supermicro H14SHM motherboard.

How much heat does the 1.1V registered ECC kit produce during continuous operation?

The 1.1V DDR5 RDIMMs run at standard server voltage without heat spreaders, relying on chassis airflow for cooling.

Which motherboard must I already own for this 256GB kit to work?

The kit is validated for the Supermicro H14SHM motherboard and requires its 288-pin RDIMM slots.
