Server-grade DDR5 ECC RDIMM kit

This 256 GB kit contains four 64 GB DDR5-5600 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SSW memory controller expects. It targets administrators who need maximum supported capacity on that specific platform without manual tuning.

Fits the H13SSW DIMM slots directly

The 288-pin Registered form factor matches the board's required RDIMM architecture; UDIMM or SODIMM modules will not work. Populating all four channels with 2Rx4 registered DIMMs offloads the memory controller and allows full-capacity operation at the rated 5600 MT/s speed.

Sustained enterprise stability

Registered buffering and on-die ECC correct single-bit errors continuously during long-running workloads, preventing silent data corruption and unplanned reboots. The 1.10 V operating voltage and CL46 latency are maintained across full population for consistent throughput under load.

Questions about this item

Will the 1.1 V registered ECC modules sustain their rated 5600 speed when all four slots of the Supermicro H13SSW are populated?

The kit is spec-matched to the board's memory-population rules, so the registered architecture lets every slot run fully populated at the rated DDR5 5600 speed.

How much heat and power should I expect from the 256 GB kit running continuously in a server chassis?

Each 64 GB module operates at 1.1 V without a heat spreader, so the registered design keeps power draw and thermals low enough for standard server airflow.

Does my Supermicro H13SSW need a specific BIOS revision or CPU stepping before it will recognise the 2Rx4 registered DIMMs?

The modules are an exact-match upgrade validated for the H13SSW motherboard; consult the system manual for approved population order and installation steps.
