Exact-match DDR5-4800 RDIMM kit for Supermicro

This 512 GB kit contains four 128 GB DDR5 Registered ECC RDIMMs rated at 4800 MHz CL40 and 1.10 V. The 2Rx4 modules match the memory controller's rank, voltage and timing requirements so the board recognises full capacity and runs at rated speed.

Who this suits and who should look elsewhere

The kit is built for administrators upgrading or populating a Supermicro H13SSL-NT motherboard with validated Registered ECC memory. It is not for systems that accept only unbuffered UDIMMs or SODIMMs, nor for builds that require a heat spreader or non-ECC operation.

Build integration

The 288-pin RDIMM form factor fits the H13SSL-NT slots and the registered architecture offloads the controller to allow full population at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. Check the motherboard manual for supported capacities, approved DIMM population order and installation steps before fitting.

Questions about this item

Does the Supermicro H13SSL-NT motherboard need to support 2Rx4 Registered ECC DDR5 RDIMMs for this kit to function?

Yes. This kit is 2Rx4 Registered ECC DDR5 RDIMM at 1.10V. The H13SSL-NT must accept that exact rank, voltage, and registered form factor to recognise all 512GB at DDR5-4800 CL40.

Can I mix these 2Rx4 DDR5 RDIMMs with other DDR5 RDIMMs of different rank or speed on the H13SSL-NT?

Mixing ranks or speeds is not recommended. The board's memory controller expects uniform 2Rx4 modules at 1.1V; mismatched DIMMs may force a lower common speed, reduce capacity, or prevent boot.

How do I verify the kit is running at DDR5-4800 CL40 1.1V with ECC active after installation?

Enter the BIOS or use a tool like dmidecode on Linux. Confirm each slot shows 128GB, 4800 MT/s, CL40, 1.1V, Registered ECC, and 2Rx4 organisation with zero correctable errors logged.
