Capacity and fit

This 32 GB DDR5 module is built for the Lenovo ThinkSystem SR780a V3 rack server. It adds a single registered ECC DIMM to expand memory capacity for virtualisation and database workloads.

Before ordering

Verify that the server has a free 288-pin DDR5 RDIMM slot and that the firmware supports 5600 MT/s registered memory at 1.10 V. Check the system manual for population rules and maximum rank limits per channel.

Build and connectors

The module uses a standard 288-pin RDIMM form factor without a heat spreader, relying on server airflow for cooling. Major OEM DRAM from Samsung, Micron or Hynix is stress tested for stability in mission-critical environments.
