Lenovo Thinkstation PX DDR5 RDIMM Kit

This 512GB kit contains sixteen 32GB DDR5 4800 ECC registered modules built for the Lenovo Thinkstation PX workstation. It delivers registered, error-correcting memory for professional workloads that require data integrity and high capacity. The 2Rx8 organisation and 1.10V operation match the platform's specifications exactly.

ECC Registered Modules for Data Integrity

Each module provides on-die ECC and registered buffering to reduce electrical load on the memory controller. This configuration helps maintain stability during sustained compute tasks such as rendering, simulation or large-dataset analysis. The CL40 latency and PC5-38400 rating are the rated speeds for this specific kit.

Verify Slot Count and BIOS Revision

Confirm the workstation has sixteen DDR5 RDIMM slots available and that the current BIOS supports 512GB of registered memory at 4800MT/s. Some configurations may limit total capacity or require a specific firmware version to recognise the full kit. Check the system documentation before ordering.

Questions about this item

Will the 16 modules need any active cooling or fan maintenance over time?

The kit has no heat spreaders, so airflow through the chassis is the only cooling required; no fans or pumps on the memory itself to service.

What caps sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s transfer rate sets the bandwidth ceiling; CL40 determines access delay but does not limit peak throughput.

How much power does the full 512 GB kit draw at 1.1 V under continuous load?

At 1.1 V each 32 GB RDIMM draws only a few watts, so the 16-module kit stays well within typical DDR5 power envelopes for registered memory.
