OWC 4GB DDR4 2133MHz CL15 1.2V 288-pin UDIMM memory upgrade for Lenovo ThinkCentre M700 SFF M800 M900 S510

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.
