Exact-match DDR5-6400 kit

This 512GB kit contains four 128GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. It is built for administrators and integrators deploying Supermicro H14DST-FL servers that require registered ECC memory at maximum capacity.

Registered ECC for full population

The 288-pin RDIMM form factor with 2Rx4 organisation lets every slot run fully populated while the registered buffer offloads the memory controller. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Low-voltage DDR5 thermals

Each module operates at 1.10V without a heat spreader, relying on server chassis airflow for cooling. The registered design reduces electrical load on the controller, keeping power draw modest and acoustic profile low in typical rack environments.

Questions about this item

Will the CL52 latency hold steady when all four slots are populated under sustained load?

The modules are rated CL52 at DDR5-6400 and the registered architecture is designed to maintain rated timings across a fully populated four-DIMM configuration.

How much heat does a fully populated 512 GB kit generate during continuous operation?

Each DIMM runs at 1.1 V without a heat spreader; registered DDR5 modules at this voltage typically stay within standard server thermal limits when chassis airflow follows the motherboard vendor's guidelines.

Does the Supermicro H14DST-FL require a specific BIOS revision or CPU stepping to recognise the full 512 GB capacity?

The kit is validated for the H14DST-FL motherboard; consult the board manual for the approved DIMM population order and any BIOS version notes before installation.
