384GB DDR5 RDIMM kit for Supermicro H13SSW

This 384GB kit contains four 96GB DDR5 6400 registered ECC RDIMMs built for the Supermicro H13SSW motherboard. It targets administrators who need maximum supported capacity on that platform and require error correction for production workloads. The registered design lets the memory controller drive all slots at rated speed without signal degradation.

Exact-match specifications remove guesswork

The modules run at 1.1V with CL52 timings and a 2Rx4 organisation, matching the board's native memory controller expectations. This alignment means the firmware recognises the full 384GB at DDR5 6400 without manual tuning or downclocking. ECC and registered buffering work together to correct single-bit errors and reduce electrical load on the controller.

Follow the motherboard population guide

Installation uses standard 288-pin RDIMM slots, but the H13SSW has specific population rules for four 96GB dual-rank modules. Consult the board manual for the correct slot order and any BIOS version requirements before seating the DIMMs. Ignoring the documented sequence is the most common cause of partial capacity detection or boot failure.

Questions about this item

Will the 96GB RDIMMs need any firmware updates or periodic reseating after installation?

No firmware updates or reseating are required; the 288-pin DDR5 RDIMMs are an exact-match upgrade that the Supermicro H13SSW memory controller recognises at full 384GB capacity and rated 6400 speed.

What is the first limit reached when all four 96GB modules run at DDR5 6400 continuously?

The CAS latency of CL52 at 1.10V sets the timing boundary; the registered 2Rx4 architecture keeps every slot stable at the rated 6400 MT/s without down-clocking.

How much heat and power do the four 96GB sticks draw during all-day operation?

Each module operates at 1.1V without a heat spreader; the registered design offloads the memory controller so total power stays at the rated voltage across all four DIMMs.
