System-Specific DDR4 Memory Kit

This Computer Memory Solutions kit provides 16GB of DDR4 memory as two 8GB DIMMs rated at 2666MHz with CL19 timings. It is built for Lenovo ThinkCentre M720S SFF and Tower desktops that require 288-pin unbuffered non-ECC modules. The 1.2V voltage and 2Rx8 rank configuration match the platform's specifications.

Ideal for ThinkCentre M720S Upgrades

This kit suits owners of a ThinkCentre M720S SFF or Tower who want to add or replace memory up to the platform's 64GB maximum across four sockets. It is not for systems that need ECC registered modules, laptop SODIMM form factors, or a different DDR generation.

288-Pin DDR4 2666MHz CL19 Specification

The decisive specification is the 288-pin DDR4 2666MHz CL19 unbuffered non-ECC DIMM standard. Only systems accepting this exact combination of pin count, speed, latency and voltage will recognise and run the modules correctly.

Questions about this item

Will the 1.2V DDR4 modules need active cooling or replacement under normal desktop use?

The kit has no heat spreader and runs at standard 1.2V; no active cooling or scheduled replacement is required for typical workloads.

What capacity ceiling hits first when all four slots of the ThinkCentre M720S are populated?

The platform supports a maximum of 64GB across its four sockets, so that total capacity limit is reached before any speed or rank restriction applies.

How much power and heat do the two 8GB sticks draw during continuous operation?

Each module operates at 1.2V without a heat spreader, so combined power draw and thermal output remain low for all-day desktop workloads.
