NEMIX RAM
Eight 96 GB DDR5 registered ECC modules at 6400 MT/s CL52 deliver 768 GB for Supermicro servers
This 768 GB kit contains eight 96 GB DDR5 6400 registered DIMMs built for Supermicro servers and workstations. ECC and 2Rx4 organisation protect data integrity in mission-critical workloads. The modules run at 1.1 V and carry a CL52 latency rating. They target IT teams that need maximum capacity per socket.
Registered DIMMs install like standard memory but the motherboard must support registered ECC DDR5 and the correct population rules. Mixing ranks or speeds can prevent boot, so fill all eight slots with identical modules. Always follow the system manual for slot order and BIOS settings. No heat spreader is fitted, so ensure adequate chassis airflow.
DDR5 6400 registered memory relies on the memory controller and BIOS to train at the rated speed; some platforms may downclock to a lower JEDEC speed. Total capacity is capped by the CPU memory-controller limit and the number of DIMM slots. Registered buffers add a small latency overhead versus unbuffered modules.
