Server-ready DDR5 kit

This 384GB kit contains four 96GB registered ECC RDIMMs built for the Supermicro H13DSH motherboard. The modules use the 288-pin DDR5 form factor and operate at 1.1V to match the platform's memory controller requirements.

Registered ECC architecture

Registered buffering offloads the memory controller so all four slots run fully populated at the rated 6400MHz speed. On-die ECC corrects single-bit errors in flight, preventing silent data corruption that would otherwise cause unplanned reboots in production workloads.

384GB capacity ceiling

Four ranks of 96GB modules fill the board's supported population for maximum density at DDR5-6400. Workloads needing more memory or higher speeds than PC5-51200 will require a different platform or memory configuration.

Questions about this item

Will the 96 GB RDIMMs need any firmware updates or periodic reseating to stay stable in the Supermicro H13DSH?

No firmware updates or scheduled reseating are required; the 2Rx4 registered ECC modules run at the board's native DDR5 6400 speed with CL52 timings once installed.

What is the first limit reached when all four slots run DDR5 6400 continuously at full load?

The memory controller's maximum supported capacity of 384 GB across four 288-pin RDIMM slots is the limiting factor before bandwidth or thermal constraints appear.

How much heat and power do the 1.1 V modules add when the server runs 24/7?

Each 96 GB RDIMM operates at 1.1 V without a heat spreader, so total power draw stays low and standard server airflow handles the thermal load.
