Exact DDR5-6400 kit for Supermicro H14DST-FL

This 32 GB kit contains two 16 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built as an exact-match upgrade for the Supermicro H14DST-FL motherboard, delivering registered ECC memory that the platform recognises at full capacity and rated speed.

Registered DDR5 requires board support for RDIMMs

The modules use the 288-pin registered DIMM form factor and will not work in systems that accept only unbuffered UDIMMs or SODIMMs. Population rules and maximum supported capacity are defined by the motherboard, so the manual must be consulted before installation to confirm slot order and total memory limits.

Enterprise-grade stability without a heat spreader

Samsung, Micron or Hynix DRAM chips provide the registered buffer that offloads the memory controller, allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. The bare-module design fits dense server chassis where tall heat spreaders would interfere with airflow or adjacent components.

Questions about this item

Should I choose the 2x16GB kit or a single 32GB module for my H14DST-FL?

The kit provides two 16GB RDIMMs that populate two channels, letting the memory controller run both ranks in parallel for full bandwidth.

What does DDR5-6400 actually deliver once installed in the Supermicro board?

The modules operate at 6400 MT/s with CL52 timing at 1.1V, giving the rated PC5-51200 throughput when the motherboard trains them at that speed.

How does the 288-pin RDIMM interface limit what I can install?

The board only accepts registered 288-pin DDR5 RDIMMs; UDIMMs or SODIMMs will not fit and unbuffered modules are not supported.
