NEMIX RAM 512GB (16x32GB) DDR5 5600 ECC RDIMM memory upgrade

Server memory kit

This 512GB kit contains sixteen 32GB DDR5 5600 ECC registered DIMMs built for the Lenovo ThinkSystem SR680a V3 rack server. Each module runs at 1.1V with a CL46 latency and uses a 1Rx4 organisation. The registered design and error-correcting code target enterprise workloads that require data integrity across all populated slots.

Sustained operation

Registered buffering reduces electrical load on the memory controller when all sixteen slots are filled, helping the platform maintain the rated 5600 MT/s transfer rate under continuous demand. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable across the full kit.

Build and connectors

Modules use the standard 288-pin DDR5 RDIMM form factor without heat spreaders, relying on server chassis airflow for cooling. Major-brand Samsung, Micron or Hynix DRAM components are assembled to meet Lenovo qualification requirements. The kit is intended exclusively for the validated platform; other systems will not accept the registered ECC pinout or firmware profile.
