32GB DDR5 ECC kit for Lenovo ThinkSystem ST50 V3

This 32GB kit contains two 16GB DDR5 5600MHz ECC unbuffered UDIMMs built for the Lenovo ThinkSystem ST50 V3 tower server. It runs at 1.1V with a CAS latency of CL46 and uses 1Rx8 organisation on 288-pin modules.

Capacity and headroom for typical server workloads

The 32GB total capacity handles common entry-level server tasks such as file sharing, light virtualisation and database services. Workloads that need larger memory pools for heavy virtualisation or in-memory analytics will exceed the available headroom.

Thermals noise and power draw in normal use

Modules operate at the standard DDR5 voltage of 1.1V without heat spreaders, relying on system airflow for cooling. Power draw stays low during typical server operation and the kit adds no moving parts or audible noise.

Questions about this item

Will the 5600MHz DDR5 ECC UDIMM modules run reliably alongside any existing DDR5 memory I keep in the Lenovo ThinkSystem ST50 V3?

The kit operates at 5600MHz with CL46 latency and 1.1V. For reliable operation, any existing DDR5 modules should match this speed, voltage and timing; mixing different specifications can cause the system to downclock or become unstable.

How can I verify the 32GB DDR5 5600MHz ECC kit is working as intended after installation in the ThinkSystem ST50 V3?

Enter the system BIOS or UEFI and confirm the memory is detected as 32GB total, running at 5600MHz (PC5-44800) with ECC active and CL46 timings applied.

What is included in the ME44800-618K2 package and what must be purchased separately for the ThinkSystem ST50 V3?

The box contains two 16GB 288-pin DDR5 ECC unbuffered UDIMM modules (32GB total). No heat spreaders, cables or additional hardware are included; the server itself provides the memory slots and cooling.
