  • 288-pin RDIMM form factor fits the board's required DIMM slots without adapters

Capacity and form factor

This 384GB kit contains twelve 32GB DDR5 RDIMM modules built for the Supermicro H14SSL-N motherboard. Each module uses a 288-pin registered design with ECC and operates at 1.1V. The 2Rx8 organisation matches the board's memory controller requirements for full-slot population.

Upgrade path and fitment

The kit replaces any lower-capacity DDR5 RDIMM configuration on the H14SSL-N when the workload demands the maximum supported module count. Registered buffering offloads the controller so all twelve slots run at the rated 6400MHz without signal degradation. ECC corrects single-bit errors in flight, preventing silent corruption that unbuffered memory cannot catch.

Headroom and limits

Twelve dual-rank modules deliver the full 384GB at CL52 latency, suitable for large in-memory databases and virtualization clusters. The fixed 1.1V operating voltage and registered topology mean the kit cannot be used in consumer UDIMM platforms or boards limited to fewer than twelve slots. Buyers needing higher per-module density or non-ECC operation must choose a different product.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the Supermicro H14SSL-N memory slots?

Yes, the 12-module kit uses the 288-pin RDIMM form factor that the H14SSL-N requires; UDIMM or SODIMM modules will not fit this board.

What is the correct population order when installing all 12 modules on the H14SSL-N?

Follow the motherboard manual's DIMM population sequence exactly; the board's memory-controller rules dictate which slots must be filled first for full 384GB recognition.

Do the modules have heat spreaders that could need cleaning or replacement over time?

No, the kit ships without heat spreaders, so there are no spreaders to clean or replace during the module's service life.
