System-specific DDR5 kit

This NEMIX RAM kit delivers 256GB across four 64GB registered DIMMs built for the SuperMicro BigTwin SuperServer SYS-222BT-HER. It targets administrators who need maximum capacity in a validated configuration for that platform.

6400MHz CL52 headroom

The modules run at 6400MHz with CAS latency 52 at 1.1V, using 2Rx4 organisation and ECC protection. Registered buffering stabilises heavy workloads, while the four-module limit of the kit matches the server's slot count.

ECC RDIMM reliability

Each stick is a 288-pin DDR5 RDIMM without a heat spreader, relying on server airflow. The package contains only the four modules; no extra cables, software or mounting hardware are included.
