Exact-Match Server Upgrade

This NEMIX RAM kit delivers 256GB across eight 32GB DDR5 Registered ECC RDIMMs rated at 6400MHz PC5-51200 with CL52 timing at 1.1V. It is built specifically for the Supermicro H14DST-FL motherboard using the 288-pin RDIMM form factor and 2Rx8 rank configuration that the board requires.

Sustained Enterprise Stability

Registered architecture buffers every address and command so all eight slots operate at full capacity under continuous load without overloading the memory controller. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads.

Low-Voltage Thermal Profile

Operating at 1.1V reduces power draw per module compared to higher-voltage server memory, helping system fans maintain lower speeds in typical rack environments. The absence of heat spreaders relies on chassis airflow, so adequate slot spacing and directed cooling are required for sustained operation.
