Exact-match DDR5 kit for Supermicro H14DST-FL

This 384GB kit contains six 64GB DDR5 RDIMMs built to the precise rank, voltage and timing the Supermicro H14DST-FL memory controller expects. It is intended for server administrators who need to populate every slot with registered ECC memory that the platform recognises at full capacity.

Registered ECC with 2Rx4 organisation

The modules use a 2Rx4 registered ECC design that offloads the memory controller and corrects single-bit errors on the fly, preventing silent data corruption when all slots are fully populated. This organisation is the single specification that determines whether the board will initialise the kit at its rated DDR5 6400 speed.

384GB total capacity across six slots

The kit delivers 384GB of addressable memory, suitable for virtualisation hosts, in-memory databases and large-scale compute workloads that fit within this limit. Workloads requiring more memory per socket or a higher module density than 64GB per DIMM will exceed what this configuration can provide.

Questions about this item

What does the DDR5 6400 speed mean when all six 64GB RDIMMs are installed in the Supermicro H14DST-FL?

The kit runs at the rated DDR5 6400 transfer rate with CL52 latency at 1.10 V when fully populated on the H14DST-FL, because the 2Rx4 registered ECC modules match the board's memory-controller expectations.

How does the 288-pin RDIMM form factor and registered ECC design affect usable bandwidth on this motherboard?

The 288-pin RDIMM layout is the only form factor the H14DST-FL accepts; registered buffering lets all six slots run at full DDR5 6400 speed while ECC corrects single-bit errors without reducing throughput.

What physical clearance and slot population rules apply to these 288-pin RDIMMs on the H14DST-FL?

Each module is a standard-height 288-pin RDIMM with no heat spreader, so it fits the H14DST-FL's DIMM slots; follow the motherboard manual's population sequence for six 2Rx4 modules to enable full 384 GB capacity.
