8 GB DDR4 module for Lenovo systems

This 8 GB DDR4 2666 MHz UDIMM is built for Lenovo ThinkSystem desktops and workstations that require non-ECC unbuffered memory. It suits IT professionals and enthusiasts upgrading compatible Lenovo platforms with a single 288-pin stick.

Capacity and headroom

The single-rank 1Rx8 module provides 8 GB at PC4-21300 speed with CL19 latency and 1.20 V operation. It handles everyday workloads and moderate multitasking, while memory-intensive tasks such as virtualisation or large datasets will exhaust the capacity.

Lenovo ThinkSystem 4ZC7A08701 compatibility

This part is validated for the Lenovo ThinkSystem 4ZC7A08701 specification using major OEM chips from Samsung, Micron or Hynix. Systems needing ECC, registered DIMMs or a different DDR generation cannot use this module.

Questions about this item

Will this DDR4 2666 MHz CL19 UDIMM work alongside existing DDR4 modules in my Lenovo ThinkSystem?

It is a 1Rx8 unbuffered non-ECC DDR4 2666 MHz CL19 1.2 V UDIMM. Mixing modules of different speeds, ranks or latencies may cause the system to run all memory at the lowest common settings.

How can I verify the module is recognised at 2666 MHz with CL19 timings after installation?

Check the system BIOS or UEFI memory information screen; it should report DDR4 2666 (PC4-21300) with CAS latency 19. Operating-system tools such as Task Manager or dmidecode will also show the configured speed and timings.

What comes in the box and is anything else required for installation?

The package contains one 8 GB 288-pin DDR4 UDIMM. No heat spreader, cables or tools are included; only a compatible Lenovo ThinkSystem desktop or workstation with a free DDR4 UDIMM slot is needed.
