NEMIX RAM DDR5 64GB 4800 CL40 1.1V 2Rx4 ECC RDIMM Supermicro H14DST-FL memory upgrade

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.
