Supermicro H13SSF 384GB DDR5 ECC RDIMM kit

This 384GB kit contains six 64GB DDR5 5600 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSF memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors so fully populated slots run at rated speed without silent data corruption. The modules operate at 1.1V with CL46 latency and use a 288-pin registered form factor that matches the board's physical and electrical requirements.

Suits H13SSF servers needing maximum registered

This kit is for administrators populating every slot on a Supermicro H13SSF motherboard with validated registered ECC memory. It is not for systems that require unbuffered UDIMMs, SODIMM form factors, lower-density modules, non-ECC operation or any DDR generation other than DDR5. Builders using different motherboards or mixed-rank configurations should verify their platform's qualified-vendor list before purchasing.

2Rx4 registered ECC at 1.1V decides fit

The 2Rx4 registered ECC organisation running at 1.1V is the single specification that determines whether this kit will be recognised at full capacity and run at DDR5 5600 on the target board. If your motherboard's memory population rules call for a different rank structure, voltage or buffering type, the modules will not operate as intended. Consult the system manual for approved DIMM population order and supported capacities before installation.

Questions about this item

Does the Supermicro H13SSF need all six 64GB RDIMM slots filled to run this 384GB DDR5-5600 kit at rated speed?

The H13SSF requires registered ECC DDR5 RDIMMs; this kit supplies six 2Rx4 modules at 1.1V CL46 so the board sees the full 384GB at 5600MHz when populated per its memory‑population rules.

Can I add these 2Rx4 CL46 1.1V modules alongside existing 1Rx4 or 2Rx8 DDR5-5600 RDIMMs in the same H13SSF?

Mixing ranks or densities on the H13SSF can change the memory controller’s addressing; the manual specifies which slot combinations are validated for full‑speed operation with registered ECC DDR5.

How do I confirm the kit is running at DDR5-5600 CL46 1.1V with ECC active after install?

Check BIOS memory info or a tool like dmidecode — each DIMM should report 64GB, 5600MT/s, CL46, 1.1V, registered ECC, and the total should show 384GB.
