Compatible Lenovo ThinkCentre M720S

This 16GB DDR4 module is built for the Lenovo ThinkCentre M720S SFF and Tower desktops. It arrives as a single unbuffered DIMM ready to expand system memory. Computer Memory Solutions validates compatibility for these specific models.

2666 MHz CL19 timing

The stick runs at 2666 MHz with a CAS latency of 19 and 19-19-19 timings. This speed and latency combination is the deciding specification for stable operation in the supported platforms. Installing a different speed or latency may prevent the system from booting correctly.

Low-voltage unbuffered design

Operating at 1.2V without a heat spreader, the module draws minimal power and runs quietly in the compact SFF chassis. The unbuffered layout keeps electrical load light on the memory controller. Thermal output stays low during typical office workloads.

Questions about this item

Will the 2666 MHz speed actually run at that rate in my ThinkCentre M720S?

The module is rated at DDR4 2666 (PC4 21300). The ThinkCentre M720S memory controller supports up to 2666 MHz, so the stick will operate at its rated speed without manual tuning.

Does the 288-pin DDR4 interface limit total capacity or rank configuration?

The 288-pin unbuffered DDR4 slot accepts this 2Rx8 16 GB module. The platform maximum is 64 GB across four sockets, so you can populate all four slots with identical sticks.

Will this 288-pin DIMM fit inside the small-form-factor M720S chassis?

Yes. The module is a standard-height 288-pin DIMM with no heat spreader, matching the clearance of the M720S SFF and Tower memory slots.
