Exact-match DDR5-5600 kit

This 64 GB kit (2 x 32 GB) delivers DDR5-5600 (PC5-44800) Registered ECC memory at 1.10 V and CL46. It is built specifically for the Supermicro H13SSW motherboard, using the 288-pin RDIMM form factor and 2Rx8 organisation that the board's memory controller expects.

Capacity and headroom

Two 32 GB modules populate two DIMM slots for a total of 64 GB, suitable for virtualisation hosts, database workloads and multi-tenant services. The registered architecture allows every supported slot to run fully populated at rated speed, while ECC corrects single-bit errors before they affect production data. Buyers who need more than 64 GB or a different DIMM population order should verify the board's maximum supported capacity and slot layout first.

Thermals and power

Modules operate at the standard DDR5 server voltage of 1.10 V without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation across all populated slots. Power draw scales with the number of active ranks; systems running fewer modules will draw proportionally less.

Questions about this item

Will this DDR5 5600 RDIMM kit work in the other slots of my Supermicro H13SSW if I keep the original memory?

The kit is spec-matched to the H13SSW population rules; install the two 32 GB modules in the recommended slot order from the motherboard manual so the controller recognises the full 64 GB at DDR5 5600.

How can I confirm the ECC RDIMM modules are running at CL46 and 1.1 V after installation?

Check the BIOS memory information or a tool such as dmidecode — it should report 5600 MT/s, CL46 timing, 1.1 V and registered ECC status for each 32 GB DIMM.

What exactly ships in the box and do I need any extra brackets or cables?

The box contains the 64 GB kit as two 32 GB 288-pin DDR5 RDIMM modules; no heat spreaders, brackets, cables or additional hardware are included or required.
