Exact DDR5 4800 ECC RDIMM for Supermicro H14DST-FL

This 64 GB registered ECC module matches the DDR5 4800 PC5-38400 specification the Supermicro H14DST-FL memory controller expects. The 2Rx4 rank layout, 1.10 V operating voltage and CL40 timing are factory-matched so the server recognises the full capacity at rated speed without manual tuning. It is intended for administrators upgrading or populating that specific motherboard with validated server memory.

Low-voltage registered design limits heat

Operating at 1.10 V, the DDR5 RDIMM reduces electrical load on the memory controller compared with higher-voltage alternatives. The registered buffer isolates each 288-pin module from the bus, allowing every slot to run fully populated at 4800 MT/s without signal degradation. No heat spreader is fitted, relying on standard server airflow to maintain thermal limits during continuous operation.

Chip-level ECC and registered buffering protect

On-die ECC corrects single-bit errors in real time, preventing silent data corruption that can crash workloads or corrupt databases. The registered architecture offloads address and command signals from the CPU memory controller, enabling stable operation when all DIMM slots are filled. Buyers needing unbuffered UDIMMs, SODIMMs or non-ECC modules for workstations or consumer boards cannot use this kit.

Questions about this item

How do I install this 64GB DDR5 4800 RDIMM in the Supermicro H14DST-FL and what slot order should I follow?

Power down the server, open the chassis, align the 288-pin key with the DDR5 slot, press firmly until the ejectors click, then populate DIMM slots in the exact sequence listed in the motherboard manual so the 2Rx4 registered modules initialise at full 64GB capacity.

What maintenance or replacement will this ECC registered module need over its service life?

The module has no heat spreader and no moving parts, so routine maintenance is limited to keeping server airflow clean; if a correctable error count rises or a hard failure occurs, the lifetime replacement warranty covers a direct swap of the 64GB DDR5 4800 kit.

What limit appears first when this 1.1V DDR5 RDIMM runs sustained workloads at 4800 MT/s?

The registered buffer and on-die ECC keep signal integrity stable, so the first ceiling is the motherboard's maximum supported capacity per channel and total DIMM count rather than a thermal or voltage throttle on the 1.10V modules themselves.
