Capacity and fit

This is a single 64GB DDR5 ECC registered DIMM built for the Lenovo ThinkEdge SE455i V3 inferencing server. It targets administrators who need to expand memory capacity in that specific platform.

Before ordering

Verify that your ThinkEdge SE455i V3 has an available 288-pin DDR5 RDIMM slot and that the system firmware supports 2Rx4 modules at 5600MHz with CL46 timing. The module operates at 1.1V and carries no heat spreader, so ensure chassis airflow meets the server’s thermal requirements.

Upgrade context

It replaces lower-capacity DDR5 RDIMMs or fills empty slots to increase total system memory for inference workloads. The jump is worthwhile when the workload exceeds the capacity of the current configuration and the platform’s qualified-vendor list includes this part number.
