Lenovo ThinkSystem ST650 V3 memory kit

This 768GB kit is built for the Lenovo ThinkSystem ST650 V3 tower server. It contains sixteen 48GB DDR5 RDIMM modules. The memory is designed for enterprise workloads that require registered ECC reliability.

DDR5 5600 registered ECC specification

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V. Each stick is a 1Rx4 registered DIMM with on-die ECC. The 288-pin form factor matches the server's memory slots exactly.

768GB capacity for large datasets

Sixteen 48GB modules fill every slot to reach 768GB total. This headroom supports heavy virtualisation, in-memory databases and large-scale analytics. Workloads that exceed this capacity would need a platform with more memory channels.
