NEMIX RAM 512GB DDR5 4800 ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR5 4800 registered DIMMs with ECC. It runs at 1.10V with CL40 latency and uses a 288-pin 2Rx4 layout. The modules are validated for Lenovo Thinkstation PX workstations.

Suited for Thinkstation PX memory expansion.

IT teams scaling a Thinkstation PX to 512GB will match the factory memory specification exactly. Systems that require unbuffered non-ECC DDR5 or a different pin count cannot use these registered modules.

512GB (8 x 64GB) DDR5 4800 registered ECC capacity

The eight-module kit delivers 512GB total across 288-pin RDIMMs operating at PC5-38400 speed. This capacity and registration type decide whether the workstation can accept the upgrade.

Questions about this item

Does the ThinkStation PX need all eight DDR5 slots filled for this 512GB kit to operate?

The kit provides eight 64GB RDIMMs totalling 512GB; install them in the eight DDR5 slots your ThinkStation PX makes available for registered ECC memory.

Will the registered ECC design of these DDR5 4800 modules work with the ThinkStation PX memory controller?

Yes — each module is a 2Rx4 registered ECC RDIMM built to the DDR5 4800 (PC5-38400) standard the workstation requires.

How can I confirm the memory is running at DDR5 4800 with ECC active after installation?

Check the BIOS or UEFI memory information screen: it should show 512GB total, 4800 MT/s speed, CL40 latency, 1.10V voltage and ECC enabled.
