NEMIX RAM 256GB (8×32GB) DDR5 6400 CL52 1.1V 2Rx8 ECC Registered RDIMM memory upgrade

Supermicro H14DSH DDR5 upgrade kit

This 256 GB kit contains eight 32 GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H14DSH motherboard. The modules arrive new and are validated to match the board's memory-population rules so every slot is recognised at full capacity. System administrators expanding memory on this platform can install the kit without guessing rank, voltage or timing.

Registered ECC RDIMM form factor

The 288-pin Registered (RDIMM) design is the single specification that decides fitment; the H14DSH requires RDIMMs and will not accept UDIMM or SODIMM modules. Each stick runs at 1.1 V with CL52 latency and a 2Rx8 organisation, exactly as the memory controller expects. Buyers whose boards need unbuffered or lower-density DIMMs cannot use this kit.

Sustained enterprise workloads

Registered buffering offloads the memory controller so all eight slots operate fully populated at rated speed during continuous operation. On-die ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots under long-running server loads. The modules have no heat spreader and rely on chassis airflow for thermal management.
