NEMIX RAM 2TB (16×128GB) DDR5 5600 CL46 4Rx4 1.1V ECC RDIMM for Lenovo ThinkSystem SR680a V3 memory upgrade

Lenovo SR680a V3 memory kit

This NEMIX RAM kit supplies 2TB of DDR5 registered ECC memory for the Lenovo ThinkSystem SR680a V3 rack server. Sixteen 128GB modules fill the platform with high-density RDIMMs built for enterprise workloads. The 4Rx4 organisation and 288-pin form factor match the server's memory architecture. IT teams can install the kit directly into compatible slots.

1.10V operation and thermal profile

Each module runs at 1.10V, keeping power draw low for dense server configurations. The DDR5 5600 speed rating delivers PC5-44800 bandwidth without requiring active cooling on the modules themselves. Registered buffering reduces electrical load on the memory controller. ECC protection corrects single-bit errors during normal operation.

Sustained load behaviour with CL46 latency

Under continuous demand the CAS latency of 46 cycles remains stable across all sixteen modules. The 4Rx4 rank structure supports consistent throughput for virtualisation and database tasks. Registered signalling maintains signal integrity during extended sessions. The kit is validated for the SR680a V3 platform to prevent compatibility-related throttling.
