Exact-match DDR5 RDIMM kit for Supermicro H13SSF

This 1 TB kit contains sixteen 64 GB DDR5-5600 registered ECC modules built to the PC5-44800 standard. Each DIMM runs at 1.1 V with CL46 timing and a 2Rx4 organisation. The 288-pin RDIMM form factor matches the memory controller requirements of the Supermicro H13SSF motherboard so the full capacity is recognised at rated speed.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller when all sixteen slots are populated, allowing stable operation at the full 5600 MT/s data rate under continuous server workloads. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption that could otherwise trigger unplanned reboots during long-running compute or database tasks.

Installation steps and common issues

The modules are keyed for 288-pin DDR5 RDIMM slots only; they will not fit UDIMM or SODIMM sockets. Before installation, consult the Supermicro H13SSF manual for the approved DIMM population sequence and maximum supported capacity per channel. A frequent issue occurs when DIMMs are inserted in the wrong slot order or when the BIOS is not updated to the version that validates the full 1 TB configuration.

Questions about this item

How much power does the 1.1V DDR5 5600 kit draw when all 16 slots run continuously?

Each module operates at 1.1V, the standard DDR5 voltage, so total draw depends on your motherboard's power delivery across all 16 populated slots.

What must the Supermicro H13SSF already have to accept this 16×64GB RDIMM kit?

The board needs 16 free 288-pin DDR5 RDIMM slots and a BIOS that supports 2Rx4 registered ECC modules at the full 1TB capacity.

Will the 2Rx4 registered ECC modules work alongside any older DDR5 DIMMs I keep in the same server?

Mixing ranks or capacities can break the memory controller's population rules; the manual should be checked for approved configurations before adding these 64GB sticks.
