128 GB DDR5-6400 ECC RDIMM kit

This 128 GB kit contains eight 16 GB DDR5-6400 registered ECC modules built for the Supermicro H14SSL-N motherboard. Each module runs at 1.1 V with CL52 latency and a 1Rx8 organisation. The registered design lets every slot operate fully populated at rated speed.

Check motherboard manual for population rules

Verify the exact DIMM population order and maximum supported capacity in your H14SSL-N documentation before ordering. The board requires 288-pin registered DDR5 RDIMMs; unbuffered UDIMMs or SODIMMs will not fit or function. Confirm the BIOS is updated to the version recommended by Supermicro for full 128 GB support.

Suited for memory-bound server workloads

This kit targets administrators expanding a single H14SSL-N system to 128 GB with validated registered ECC modules. It is not for desktop boards that accept only unbuffered memory, nor for servers needing a different DIMM form factor or voltage. Buyers who require higher density per module or a different registered rank configuration should look at other qualified kits.

Questions about this item

Does the 128GB kit include all eight 16GB modules or must any be purchased separately?

The package contains the complete 128GB kit with eight 16GB DDR5 RDIMMs; nothing extra is required to reach the full capacity.

Why is this 6400MHz CL52 1.1V Registered ECC kit the correct choice for the Supermicro H14SSL-N?

It matches the board's required 288-pin RDIMM form factor, 1Rx8 rank structure, registered architecture, ECC support and exact voltage and timing the memory controller expects.

What does the 6400MHz rating mean once the modules are installed in the H14SSL-N?

The server's memory controller will recognise the kit at its rated DDR5-6400 speed with CL52 latency, allowing all eight slots to run fully populated at the specified throughput.
