Capacity and fit

This 96GB kit ships as two 48GB DDR5 RDIMMs built for the Supermicro H13SST-GC motherboard. The 288-pin registered ECC modules match the board's required form factor and population rules so the system recognises the full capacity at its rated speed.

Speed headroom and limits

Rated at DDR5-6400 (PC5-51200) with CL52 latency and 1.1V operation, the kit delivers the bandwidth the platform expects for memory-intensive workloads. The registered 2Rx8 organisation keeps every slot stable when fully populated, while ECC corrects single-bit errors before they affect production data.

Thermals and power in use

Running at the specified 1.1V, the modules draw minimal power and operate without heat spreaders in typical server airflow. Registered buffering reduces electrical load on the memory controller, helping keep temperatures and noise low during sustained operation.

Questions about this item

Will this 96 GB DDR5 6400 kit run with the existing 48 GB modules already in my Supermicro H13SST-GC?

The kit uses 2Rx8 registered ECC DDR5 at 1.1 V and CL52; mixing ranks or speeds can prevent full-capacity recognition, so populate slots following the motherboard manual's approved order.

How can I confirm the memory is operating at DDR5 6400 with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 6400 MT/s, registered ECC, 2Rx8 organisation and 1.1 V.

Does the package contain only the two 48 GB RDIMMs or are heat spreaders and cables included?

The box holds the two 48 GB 288-pin DDR5 RDIMMs only; no heat spreaders, cables or additional accessories are supplied.
