Exact-Match DDR5 Kit

This 64GB kit contains two 32GB DDR5 4800 Registered ECC RDIMMs built to the Supermicro H14SSF memory-controller specification. It targets administrators who need the board to recognise full capacity at rated speed without manual tuning.

Registered Architecture Fit

The 288-pin RDIMM form factor and 2Rx8 organisation match the motherboard's population rules, allowing every slot to run fully populated at 1.1V. Registered buffering reduces electrical load on the controller so stability scales with capacity.

ECC Protection Included

On-die ECC corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads. The kit ships as a matched pair with no heat spreaders, relying on server chassis airflow for thermal management.

Questions about this item

Will the DDR5-4800 CL40 registered ECC modules stay stable when all slots on my Supermicro H14SSF are populated continuously?

The registered architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly.

How much heat and power do two 32 GB 1.10 V DDR5-4800 RDIMMs add when the server runs all day?

Each module operates at 1.10 V with no heat spreader, so thermal output stays low; registered buffering reduces electrical load on the motherboard compared with unbuffered DIMMs.

What motherboard feature must my Supermicro H14SSF already have for this 288-pin RDIMM kit to work?

The board must provide 288-pin DDR5 RDIMM slots that support registered ECC memory population rules.
