16GB DDR4 2666MHz UDIMM for ThinkCentre

This OWC module is a 16GB DDR4 2666MHz PC4-21300 CL19 1.2V 288-pin non-ECC unbuffered UDIMM. It is validated for Lenovo ThinkCentre M720e, M720s, M720t, M725s and M75s-1 desktops. The 2Rx8 rank configuration meets JEDEC and RoHS standards for a warranty-safe upgrade.

Suits ThinkCentre owners adding 16GB.

Builders upgrading the listed ThinkCentre models with a single 16GB stick will find this module a direct fit. Systems that require ECC error correction, registered buffering, SODIMM form factors, or capacities beyond 16GB per slot cannot use this part.

288-pin DDR4 2666MHz non-ECC UDIMM decides fit

The decisive specification is the 288-pin DDR4 2666MHz non-ECC unbuffered UDIMM form factor. Only motherboards accepting this exact pin layout, voltage and signalling will recognise the module. Backward compatibility with 2133MHz and 2400MHz buses is supported.

Questions about this item

Should I pick the 16GB DDR4 2666MHz CL19 module or a different capacity for my ThinkCentre M720?

This module is a single 16GB stick. If your board has free 288-pin slots you can add it alongside existing memory, or use it as the only module for 16GB total.

What does the 2666MHz speed actually deliver once the module is installed in a ThinkCentre M725s?

The system will run the memory at 2666MHz CL19 at 1.2V. If the CPU or chipset only supports 2133MHz or 2400MHz, the module automatically downclocks to match.

Is the PC4-21300 rating just a label or does it limit real-world bandwidth?

PC4-21300 is the JEDEC peak transfer rate for DDR4-2666. In practice the memory controller caps throughput to that figure, so sustained bandwidth cannot exceed it.
