Supermicro H13SSL-NT 768GB Kit

This 768GB kit contains twelve 64GB DDR5 5600 Registered ECC RDIMMs built for the Supermicro H13SSL-NT motherboard. The modules run at 1.1V with CL46 latency and a 2Rx4 organisation. They are intended for servers that require maximum registered memory capacity with error correction.

Installation Notes

Each module uses the standard 288-pin RDIMM form factor and must be seated in the exact slot order the board manual specifies. The registered buffer and ECC logic mean the memory controller recognises every populated slot at the rated DDR5 5600 speed. No heat spreader is fitted, so airflow across the DIMMs must follow the chassis design.

Sustained Load Behaviour

Under continuous operation the registered architecture keeps electrical loading on the memory controller low even with all twelve slots filled. ECC corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. The 1.1V operating voltage and DDR5 5600 signalling maintain stable throughput without exceeding the platform's thermal envelope.

Questions about this item

How do I verify the 768GB kit is running at DDR5 5600 with CL46 after installation?

Enter the BIOS or UEFI on the Supermicro H13SSL-NT and confirm the memory speed shows 5600 MT/s (PC5-44800) and CAS latency 46; the registered ECC RDIMM design ensures all 12 modules initialise at the rated voltage of 1.1V.

What comes in the box and do I need any extra parts to populate the Supermicro H13SSL-NT?

The package contains twelve 64GB DDR5 5600 CL46 1.1V 2Rx4 288-pin ECC registered RDIMMs for a total of 768GB; no additional cables, brackets or cooling are required — just follow the board's DIMM population order in its manual.

Should I choose this 12 x 64GB kit or a different capacity for the H13SSL-NT?

Select this 768GB (12 x 64GB) kit when the Supermicro H13SSL-NT configuration calls for the maximum supported capacity with 2Rx4 registered ECC modules; match the exact rank, voltage and timing your motherboard's memory controller expects.
