Lenovo ThinkCentre DDR4 Upgrade

This 8GB DDR4 module is built for Lenovo ThinkCentre M720e, M720s, M720t, M725s and M75s-1 desktops. It plugs directly into a 288-pin UDIMM slot and runs at 2666MHz with CL19 latency. The non-ECC unbuffered design matches the factory specification for these systems.

Low-Voltage Standard Operation

The stick operates at the JEDEC-standard 1.2V, drawing minimal power and producing no extra heat beyond what the chassis already handles. No heat spreader is fitted, so the module relies on normal case airflow. Backward compatibility with 2133MHz and 2400MHz buses means it will clock down automatically if the platform requires it.

Single-Slot Capacity Boost

The 1Rx8 layout occupies one DIMM slot, leaving any remaining slots free for further expansion up to the board limit. Installation is a tool-less DIY task that does not void the system warranty. Buyers needing ECC error correction or registered buffering should look elsewhere, as this module provides neither.

Questions about this item

How do I install the 288-pin UDIMM in a ThinkCentre M720s, and what step do people often miss?

Power off and unplug the PC, open the case, align the notch on the 288-pin module with the slot key, press firmly until both side clips click, then power on and verify 2666 MHz in BIOS — the step most skip is confirming the speed after boot.

What maintenance or replacement will this 8 GB DDR4 module need later?

No routine maintenance is required; the unbuffered non-ECC DRAM has no moving parts or heat spreader, so replacement is only needed if a memory test reports errors or you upgrade capacity.

What limit appears first under sustained heavy workloads with this CL19 1.2 V kit?

The CAS latency of CL19 at 2666 MHz sets the timing ceiling; under continuous load the fixed latency and voltage become the bottleneck before thermal or capacity limits.
