Server DDR5 ECC RDIMM 32GB

This 32GB DDR5 5600 ECC registered DIMM is built for the Lenovo ThinkSystem ST650 V3 tower server. It targets administrators expanding memory capacity in compatible enterprise systems that require registered error-correcting modules.

Installation notes

The module uses a standard 288-pin DDR5 RDIMM form factor and installs in minutes by seating it in an available DIMM slot. Ensure the server's memory configuration rules are followed, such as population order and rank limits, to avoid boot failures or reduced performance.

Capacity and headroom

A single 32GB rank-2Rx4 module adds substantial capacity for virtualization, databases, or large datasets. Headroom depends on the number of populated channels and the processor's maximum supported memory; the module runs at 1.1V CL46 within the platform's qualified speed of 5600 MT/s.

Questions about this item

How can I confirm the module is running at 5600 MHz with CL46 timing after installing it in the Lenovo ThinkSystem ST650 V3?

Enter the system BIOS or UEFI during boot and open the memory information screen; it will show the detected speed as 5600 MT/s and the active CAS latency as CL46 for this 32 GB RDIMM.

What is included in the package and what additional parts are required for installation?

The box contains one 32 GB 288-pin DDR5 ECC RDIMM; no extra cables, brackets or heat spreaders are needed — just an available DDR5 RDIMM slot on the compatible Lenovo server motherboard.

Should I choose the 2Rx4 32 GB version or a different capacity for the ThinkSystem ST650 V3?

This specific part number MR44800-324K1 provides a single 32 GB 2Rx4 registered module; select it when you need one 32 GB stick, or buy multiple identical units to reach the total capacity your server configuration requires.
