Lenovo ThinkStation PX DDR5 ECC upgrade

This 16 GB DDR5 registered DIMM is built for the Lenovo ThinkStation PX workstation. It adds ECC-protected memory to systems that require registered modules for stability in professional workloads. The single-rank 1Rx8 organisation keeps electrical loading low on the memory controller. It runs at the platform-standard 4800 MT/s data rate.

Install in minutes with standard DIMM slots

The 288-pin RDIMM fits directly into the workstation's DDR5 slots without tools or adapters. No heat spreader is fitted, so clearance inside dense chassis is not an issue. The module operates at the standard 1.10 V, so no BIOS voltage adjustment is required. Always follow the system manual for population order and maximum module count.

16 GB capacity for memory-bound tasks

A single 16 GB module extends usable memory for virtualization, large datasets and multi-application workflows. Registered ECC operation corrects single-bit errors to maintain data integrity under sustained load. The CL40 latency and 4800 MT/s speed match the platform specification. Capacity headroom ends when all DIMM slots are populated or the workstation's maximum supported memory is reached.

Questions about this item

How do I verify the CL40 timing is active after installing the module?

Enter the system BIOS on the ThinkStation PX and confirm the memory frequency reads 4800 MT/s with a CAS latency of 40 at 1.10 V.

What is included in the package and what must be sourced separately?

The box contains one 16 GB DDR5 4800 CL40 1Rx8 ECC RDIMM; no heat spreader, tools or additional modules are supplied.

Which capacity and rank should I choose for a single-slot upgrade?

Select the 16 GB 1Rx8 version (part MR38400-618K1) for a single populated DIMM slot.
