16 GB DDR5 ECC UDIMM for ST250 V3

This 16 GB DDR5 5600 MHz CL46 module adds ECC unbuffered memory to the Lenovo ThinkSystem ST250 V3 tower server. The single 1Rx8 stick runs at 1.1 V and uses a standard 288-pin DDR5 interface. It targets administrators who need to expand server capacity with validated, system-specific RAM.

Installation notes and common issues

The DIMM slots are accessible after removing the server cover, so the upgrade takes a few minutes with no tools beyond a screwdriver. Align the notch on the 288-pin edge connector before pressing firmly until the retention clips click. The most frequent error is seating the module incompletely, which causes the system to report reduced capacity or fail POST.

Pre-order checklist

Confirm the ST250 V3 currently has an available UDIMM slot and that the memory population rules for the installed CPU allow a 1Rx8 module. Verify the BIOS is updated to a version that supports DDR5 5600 operation. Ensure the chassis airflow path is clear, as the module has no heat spreader and relies on system cooling.

Perguntas sobre este artigo

How can I confirm the DDR5 5600MHz CL46 ECC UDIMM is detected and running at 5600MT/s after installation?

Enter the BIOS or UEFI on the ThinkSystem ST250 V3 and verify the memory information screen shows 16GB at 5600MT/s with ECC active and CL46 timings; the server POST will also report the capacity and speed if the module is seated correctly.

What ships with the module and what must be sourced separately?

The box contains one 16GB DDR5 5600MHz PC5-44800 1Rx8 1.1V CL46 288-pin ECC unbuffered UDIMM; no heat spreader, cables, tools or additional DIMMs are included.

Which capacity and rank should I choose for a single-slot upgrade on the ThinkSystem ST250 V3?

This part number ME44800-618K1 provides a single 16GB 1Rx8 DDR5 ECC UDIMM; select it when you need one 16GB module rather than a multi-module kit or a different rank configuration.
