288 GB DDR5-6400 ECC RDIMM kit

This NEMIX RAM kit delivers 288 GB of DDR5-6400 registered ECC memory in six 48 GB modules. It is built for the Supermicro H14DST-FL motherboard and matches the board's required 288-pin RDIMM form factor, 2Rx8 rank structure, 1.10 V operating voltage and CL52 latency.

Suited for fully populated server builds

The kit suits administrators who need maximum supported capacity on this specific platform with registered ECC stability. It is not for systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC operation or lower voltages than 1.10 V.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller so all six slots can run continuously at DDR5-6400 without signal degradation. ECC corrects single-bit errors in real time, preventing silent data corruption during extended compute or database workloads.

Questions about this item

Will the Supermicro H14DST-FL motherboard recognise all 288GB when I install this 6x48GB DDR5 6400 CL52 ECC RDIMM kit?

The kit is spec-matched to the H14DST-FL's memory population rules, so the board recognises the full 288GB at DDR5 6400 speed with CL52 timing and 1.1V operation.

Can I keep my existing DDR5 RDIMMs and add this 6x48GB kit alongside them?

Mixing different capacities, ranks or speeds can prevent the server from posting; populate all slots with identical 48GB 2Rx8 modules for stable operation.

How do I confirm the memory is running at DDR5 6400 with ECC active after installation?

Enter the BIOS or use a hardware inventory tool; verify the reported speed shows 6400 MT/s, CL52 latency, 1.1V and that ECC status reads enabled.
