768GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit delivers 768GB of DDR5 4800 registered ECC memory across twelve 64GB modules. It is built for THINKMATE Supermicro SuperServer 111C-NR and 121C-TN2R or TN10 platforms that require registered DIMMs with error correction. The 2Rx4 organisation and 1.1V operating voltage match the server motherboard specifications. Buyers needing consumer DIMMs or non-ECC memory cannot use this kit.

Sustained Load Behaviour

Registered buffering and on-die ECC maintain data integrity during continuous server workloads such as virtualisation, database hosting or scientific compute. The CL40 latency and PC5-38400 transfer rate provide deterministic throughput across all twelve slots without the timing variability seen in unbuffered modules. Systems that demand consumer-grade overclocking headroom or lower latency timings will not benefit from this registered design.

Thermals and Power Draw

Modules operate at the standard DDR5 1.1V without heat spreaders, relying on chassis airflow for cooling in dense 12-DIMM configurations. Registered architecture adds minimal power overhead per module while enabling the full 768GB capacity. Builds with restricted airflow or enthusiast cooling expectations should verify case clearance and fan profiles before installation.
