  • 576 GB capacity from twelve 48 GB modules maximises the Supermicro H13SSF memory limit
  • DDR5 4800 CL40 at 1.1 V matches the board's rated speed and voltage exactly
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors automatically
  • 2Rx8 dual-rank organisation enables full-slot population without signal degradation
  • 288-pin DDR5 RDIMM form factor fits the H13SSF DIMM slots precisely

Exact-match DDR5 kit for Supermicro H13SSF

This 576GB kit contains twelve 48GB DDR5 4800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSF memory controller expects. It is intended for administrators who need the full capacity recognised at rated speed without manual tuning.

Verify DIMM population rules before ordering

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps to ensure the twelve modules are accepted in the correct slots.

Registered architecture reduces controller load

Registered buffering offloads the memory controller so every slot runs fully populated at full capacity while ECC corrects single-bit errors on the fly. The modules operate at 1.1V with no heat spreader, relying on chassis airflow for cooling during normal operation.

Questions about this item

Does the kit include all twelve 48 GB RDIMMs or must any modules be purchased separately?

The kit ships as a complete 576 GB set containing twelve 48 GB DDR5 4800 CL40 1.1 V ECC Registered 288-pin RDIMMs; nothing else is required to reach the full capacity.

When should I choose this 576 GB 12-module kit instead of a smaller DDR5 4800 CL40 RDIMM kit?

Select this kit when your Supermicro H13SSF motherboard supports the full 576 GB population and your workload needs the maximum registered ECC capacity across all twelve slots.

What does the DDR5 4800 CL40 1.1 V rating mean once the modules are installed in the H13SSF?

The memory controller will recognise each 2Rx8 RDIMM at its rated 4800 MT/s speed, CL40 latency and 1.1 V voltage, delivering the full 576 GB with registered ECC stability.
