Lenovo ThinkSystem ST650 V3 DDR5 kit

This 256 GB kit contains eight 32 GB DDR5 5600 registered ECC modules built for the Lenovo ThinkSystem ST650 V3 tower server. The 2Rx4 RDIMM design delivers error-correcting capacity for demanding enterprise workloads.

Check DDR5 RDIMM slot count and population rules

Verify that your ST650 V3 has eight available DDR5 RDIMM slots and review the server documentation for supported memory configurations before ordering. The kit runs at 1.1 V with CL46 latency and requires a platform that accepts registered DDR5 DIMMs.

288-pin registered modules without heat spreaders

Each module uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.10 V without integrated heat spreaders. Ensure the server chassis provides adequate airflow across the memory bays for stable daily operation.
