System-specific DDR4 upgrade

This 4 GB DDR4 module is built for Lenovo ThinkCentre M700 SFF, M800, M900 and S510 desktops. It plugs directly into a 288-pin UDIMM slot and runs at the standard 1.2 V. The unbuffered, non-ECC design matches the original equipment specification for these systems.

Capacity and headroom

A single 4 GB stick adds modest capacity for everyday office tasks, web browsing and light multitasking. It will not satisfy workloads that need large memory footprints such as virtualisation, heavy content creation or large dataset processing. Buyers who need more than 4 GB per slot should look for higher-density modules.

CL15 latency at 2133 MHz

The module operates at DDR4-2133 (PC4-17000) with a CAS latency of CL15. This timing is the key specification that determines compatibility with the memory controller in the listed ThinkCentre models.

Questions about this item

Will this 288-pin DDR4-2133 CL15 1.2V module run alongside the original memory in my ThinkCentre M700 SFF?

Yes, the module is JEDEC-standard DDR4-2133 CL15 1.2V, so it will operate at the same speed, latency and voltage as the factory-installed memory in the M700 SFF, M800, M900 and S510.

How can I verify the 4GB stick is detected at the correct 2133MHz CL15 after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show 4GB, DDR4-2133 (PC4-17000) and CAS latency 15.

Does the package include only the UDIMM or are any tools or brackets supplied?

Only the 4GB 288-pin non-ECC UDIMM is included; no tools, brackets or additional cables are provided.
