NEMIX RAM
16 GB DDR5 4800 ECC RDIMM server memory module with CL40 latency and 1.1 V operation
This NEMIX RAM module delivers 16 GB of DDR5 4800 ECC registered memory for Micron server and workstation platforms. The single 1Rx8 rank operates at 1.10 V with CL40 latency, providing error correction and signal buffering required by registered DIMM architectures. It targets IT professionals upgrading or populating compatible Micron systems.
The module fits a standard DDR5 288-pin RDIMM socket and relies on the motherboard's registered buffer and ECC logic. No heat spreader is included, so airflow across the PCB must be supplied by the chassis or ducting. It frees the builder from sourcing vendor-specific kits while maintaining OEM-level validation.
At 16 GB the stick handles typical virtualization, database and AI inference workloads that fit within a single channel. The CL40 latency and 4800 MT/s rate set the performance ceiling; applications demanding higher bandwidth or lower latency will exceed this module's headroom.

The module runs at 1.10V as specified for DDR5 ECC RDIMM operation.
No heat spreader is fitted; thermal performance depends on system airflow across the 288-pin module.
The board must provide DDR5 RDIMM slots with ECC and registered-buffer support.
