Targeted Lenovo Desktop Upgrade

This 4 GB DDR4 module is built for Lenovo S510 SFF and Tower units as well as ThinkCentre M700 SFF and Tower systems. It installs in a standard 288-pin DIMM slot and runs at 2400 MHz with CL17 latency at 1.2 V.

Who This Suits And Who Should Look Elsewhere

Owners of the listed Lenovo desktops who need a single non-ECC stick to reach the platform limit of 64 GB across four slots will find this part a direct match. Buyers who want ECC error correction, a heat spreader, higher frequencies or a multi-stick kit should choose a different module.

Deciding Specification — 288-Pin DDR4 2400 MHz

The key detail is the combination of 288-pin DDR4, 2400 MHz speed, non-ECC unbuffered design and 1.2 V operation. If your system requires any other pin count, voltage, ECC type or speed this module will not work.

Questions about this item

How do I install the CM512642400DIMM module into a Lenovo ThinkCentre M700 SFF, and which step is most often missed?

Power off and unplug the system, open the chassis, align the 288‑pin DDR4 module with the slot notch, press firmly until the retention clips click, then close the case. The step most often missed is verifying the clips have fully latched on both ends before powering on.

What maintenance or replacement will this 4 GB DDR4 2400 MHz CL17 stick need over its lifetime?

No scheduled maintenance is required; keep the interior dust‑free and ensure airflow. If errors appear, the module is covered by a limited lifetime warranty from Computer Memory Solutions for exchange.

What is the first limit reached when this 2Rx8 unbuffered kit runs under sustained load in a four‑slot Lenovo S510?

The platform maximum of 64 GB across four slots is the first hard limit; the module itself operates at its rated 1.2 V and CL17 timings within standard DDR4 thermal range.
