Exact-match DDR5-5600 upgrade for Supermicro H13SSF

This 256GB kit supplies sixteen 16GB DDR5-5600 Registered ECC RDIMMs built to the precise rank, voltage and timing the H13SSF memory controller expects. It is intended for administrators who need to maximise the board's supported capacity with modules that are recognised at full speed on first boot.

Capacity and headroom for dense workloads

The sixteen 1Rx8 modules deliver 256GB of registered ECC memory, allowing every slot to run fully populated at the rated 5600MT/s data rate. Registered architecture offloads the memory controller so the full complement remains stable, while on-die ECC corrects single-bit errors before they reach production workloads.

Thermals and power in normal operation

Modules operate at the standard DDR5 1.1V without heat spreaders, relying on server chassis airflow for cooling. The registered design reduces electrical load per pin, keeping power draw predictable across all sixteen DIMMs during sustained operation.

Questions about this item

Will the 16x16GB DDR5 5600MHz RDIMM kit run at full speed on a Supermicro H13SSF with older DDR5 modules already installed?

This kit is spec-matched to the H13SSF memory controller for DDR5-5600 CL46 1.1V 1Rx8 registered operation. Mixing with other modules may force the controller to downclock or disable ECC; the board manual lists approved population rules.

How can I confirm the 256GB kit is recognised at full capacity and ECC is active after installation?

Enter BIOS and verify 256GB total with all 16 slots populated at 5600 MT/s; enable ECC scrubbing and check the SMBIOS memory array for 'Multi-bit ECC' status.

Does the 16-module RDIMM kit include heat spreaders or a screwdriver, or must I buy them separately?

The package contains only the 16x16GB 288-pin RDIMM modules; no heat spreaders or tools are included.
