  • 384 GB total capacity lets your Supermicro H13SSH handle large workloads
  • DDR5-4800 speed matches the motherboard's rated memory frequency
  • Registered ECC design corrects single-bit errors to prevent silent data corruption
  • 2Rx4 organisation with 1.1 V operation meets the board's exact electrical requirements
  • Six 64 GB modules fill every slot for maximum supported density

Exact-match upgrade for Supermicro H13SSH

This 384GB kit contains six 64GB DDR5 RDIMM modules built to the exact rank, voltage and timing the H13SSH memory controller expects. Registered ECC architecture ensures every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

Kit includes six registered DIMMs only

No heat spreaders, cables or software are bundled. The modules arrive as a matched 6x64GB set so the board recognises the full 384GB capacity at DDR5-4800 without manual configuration.

2Rx4 registered ECC at 1.1V

The dual-rank x4 organisation and registered buffer are the single specification that decides compatibility; the H13SSH requires this exact layout to populate all channels at full capacity. Systems needing UDIMM, SODIMM or a different rank structure cannot use this kit.

Questions about this item

Will the 2Rx4 registered DIMM layout require any special handling or replacement schedule compared to unbuffered modules?

Registered ECC DIMMs do not wear out differently from unbuffered modules; they simply offload the memory controller so all six slots can run fully populated. No periodic replacement is needed — the modules are rated for continuous server duty and carry a lifetime warranty.

What limits sustained throughput on this 384 GB kit when all six channels are populated at DDR5-4800 CL40?

The memory controller on the Supermicro H13SSH board sets the practical ceiling; with six 64 GB 2Rx4 RDIMMs installed the kit runs at its rated 4800 MT/s and CL40 timings, so the controller's maximum supported bandwidth becomes the first bottleneck.

How much heat and power should I budget for six 1.1 V RDIMMs running 24/7 in a dense server chassis?

Each module operates at 1.10 V without a heat spreader; total power draw is low for DDR5 registered memory, and the open design relies on normal chassis airflow. No extra cooling beyond standard server ventilation is required.
