384GB DDR5 ECC RDIMM kit for Supermicro H14DST-FL

This 384GB kit contains twelve 32GB DDR5 4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DST-FL memory controller expects. It is designed for administrators who need to populate every slot at full capacity without compatibility guesswork.

Registered 288-pin form factor with 1.10V operation

The 288-pin RDIMM layout matches the board's physical and electrical requirements, while the registered architecture buffers address and command signals so all twelve slots run stably when fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

DDR5-4800 bandwidth ceiling at CL40

The PC5-38400 interface tops out at 4800 MT/s, so throughput is capped by the memory controller's maximum supported data rate regardless of how many modules are installed. Verify your system manual for approved DIMM population order and any per-channel limits before installation.

Questions about this item

Does DDR5 4800 (PC5-38400) run at its rated speed on the Supermicro H14DST-FL?

Yes, the kit is spec-matched to the board's memory controller so all 12 modules operate at DDR5 4800 with CL40 timings at 1.1V.

What physical slot and form factor do these 12 x 32GB modules require?

They are 288-pin DDR5 RDIMMs; the H14DST-FL has 12 DDR5 RDIMM slots and cannot accept UDIMM or SODIMM modules.

What population order should I follow when installing the 12 modules?

Consult the H14DST-FL manual for the approved DIMM population sequence; installing in the wrong order can prevent the system from recognising the full 384GB capacity.
