Exact-match DDR5 kit for Supermicro H13SSF

This 192GB kit delivers four 48GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the H13SSF memory controller expects. It is intended for administrators who need the full 192GB capacity recognised at rated speed without manual tuning.

Verify population rules and slot order first

The H13SSF manual defines supported capacities, approved DIMM population order and installation steps that differ by BIOS revision. Only Registered 288-pin RDIMMs are accepted; UDIMMs or SODIMMs will not seat or function. Confirm your configuration matches the board's requirements before ordering.

Registered ECC design runs fully populated

Registered architecture offloads the memory controller so every slot operates at full capacity, while on-die ECC corrects single-bit errors before they reach production workloads. Modules operate at 1.1V without heat spreaders, relying on server chassis airflow. The 288-pin RDIMM form factor locks securely into the board's DDR5 slots for long-term reliability.

Questions about this item

Does the 192GB kit ship as four 48GB modules or do I need to buy extra DIMMs?

The package contains four 48GB DDR5 RDIMMs for a total of 192GB; no additional modules are required.

Why choose the 4800 CL40 2Rx8 version over other DDR5 speeds or ranks?

This exact 4800 MT/s CL40 2Rx8 registered ECC specification matches the Supermicro H13SSF memory controller requirements for full-capacity recognition.

What does the 4800 MT/s rating deliver once installed in the H13SSF?

The modules run at the board's native DDR5-4800 data rate with ECC error correction and registered buffering for stable full-population operation.
