Lenovo ThinkSystem ST650 V3 memory upgrade

This 48GB DDR5 module is built for the Lenovo ThinkSystem ST650 V3 tower server. It delivers registered ECC memory for workloads that demand data integrity and stable uptime. The single 48GB stick fits directly into a 288-pin DDR5 slot without additional configuration.

48GB capacity with CL46 latency

The module runs at 5600MHz (PC5-44800) with a CAS latency of 46 and operates at 1.1V. Registered buffering and 1Rx4 organisation provide the headroom needed for virtualisation, databases and multi-user applications. Systems requiring more than 48GB per channel or lower latency timings will need additional or different modules.

Registered ECC RDIMM without heat spreader

Major OEM chips from Samsung, Micron or Hynix underpin the build quality. The bare 288-pin PCB keeps the profile low for dense server configurations. Installers should verify the ST650 V3 memory population rules, as registered DIMMs must follow the platform's slot order and maximum rank limits.

Questions about this item

Will this 48GB DDR5 5600MHz ECC RDIMM run alongside existing DDR5 RDIMMs in my ThinkSystem ST650 V3?

Yes, it is a 288-pin DDR5 RDIMM at 1.1V with CL46 timing. Match speed, voltage, rank and ECC type across all slots for stable operation.

How can I verify the module is recognised at 5600MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 48GB, 5600MHz, 1Rx4 organisation and ECC enabled.

What comes in the package and do I need any extra brackets or cables?

The box contains one 48GB DDR5 5600MHz PC5-44800 1Rx4 1.1V CL46 288-pin ECC RDIMM. No brackets, cables or additional parts are required.
