Exact DDR5-5600 RDIMM kit for Supermicro H13SSH

This 64 GB kit contains four 16 GB DDR5-5600 (PC5-44800) registered ECC RDIMMs built to 1Rx8 rank, 1.10 V and CL46. It is designed for administrators upgrading a Supermicro H13SSH motherboard that requires 288-pin registered modules with on-die ECC for production workloads.

Installing the four modules

Align each 288-pin RDIMM with the motherboard slots following the population order in the Supermicro H13SSH manual, then press firmly until the retention clips lock. The registered buffer reduces electrical load so all four slots can run populated at the rated 5600 MT/s, but mixing these sticks with UDIMMs, SODIMMs or different ranks will prevent the system from posting.

DDR5-5600 registered ECC limits

The JEDEC DDR5-5600 standard caps transfer rate at 5600 MT/s and voltage at 1.1 V, so the kit cannot exceed those figures even if the board supports faster profiles. Registered ECC adds a clock cycle of latency versus unbuffered modules, and the fixed 1Rx8 organisation means total capacity is limited to the four modules supplied; larger configurations would require a different motherboard or higher-density DIMMs.

Questions about this item

How can I confirm the 64GB kit is running at DDR5 5600 CL46 after installation?

Enter the system BIOS or UEFI and verify the memory speed shows 5600 MT/s with timings at CL46 and voltage at 1.10V; the Supermicro H13SSH should detect the 1Rx8 registered ECC modules automatically and report full 64GB capacity.

What comes in the package and do I need any extra parts for the Supermicro H13SSH?

The box contains four 16GB DDR5 288-pin RDIMMs totalling 64GB; no additional brackets, cables or heat spreaders are required for the H13SSH motherboard.

Should I choose this 64GB 4×16GB kit or a different capacity for my H13SSH?

Select this 64GB kit when your workload needs the full capacity across four slots at DDR5 5600 CL46; if the board manual limits population to fewer DIMMs or a lower total, choose a smaller matched kit instead.
