NEMIX RAM
A 128GB DDR5 4800 registered ECC module built for Lenovo ThinkSystem servers with AMD processors
This module is a single 128GB DDR5 4800 RDIMM built with 8Rx4 organisation and CL40 latency. It is designed for AMD processor based Lenovo ThinkSystem servers that require registered ECC memory.
Verify that your Lenovo ThinkSystem model supports DDR5 4800 RDIMM modules and accepts 8Rx4 rank configurations. Confirm the system BIOS is updated to recognise 128GB density per slot and that the motherboard provides 288-pin DDR5 slots for registered memory.
This part replaces lower density DDR5 RDIMMs or upgrades a system from smaller registered modules to 128GB per slot. The jump is worthwhile when workloads demand maximum registered ECC capacity per channel and the platform supports the 8Rx4 organisation at 4800 MT/s.
