8GB DDR4 2666MHz DIMM for ThinkCentre M720S

This 8GB DDR4 module is built specifically for the Lenovo ThinkCentre M720S SFF and Tower systems. It runs at 2666MHz with CL19 latency and 1.2V voltage. The unbuffered, non-ECC design uses a 2Rx8 rank configuration. It targets users upgrading compatible ThinkCentre desktops to the supported maximum of 64GB across four sockets.

Check motherboard slots and current memory

Before ordering, confirm your ThinkCentre M720S has a free 288-pin DDR4 DIMM slot. The system supports up to 64GB total across four sockets. Verify the existing installed modules match DDR4 2666MHz speed and non-ECC type for best compatibility. This kit includes a single 8GB stick; ensure your configuration allows adding one module without exceeding the slot count.

Single stick simplifies incremental upgrades

The package contains one 8GB memory stick with no heat spreader. This lets you add capacity in precise 8GB steps rather than buying a matched pair. Computer Memory Solutions guarantees compatibility with the listed ThinkCentre models and provides a limited lifetime warranty when purchased directly. The module uses major brand chipsets to reduce incompatibility risk.

Questions about this item

Does the box contain only the memory module or are cables and brackets included?

The package contains one 8 GB DDR4 2666 MHz DIMM stick; no cables, brackets or extra hardware are supplied.

Should I choose the 8 GB stick or look for a larger single module for my ThinkCentre M720S?

The system supports up to 64 GB across four slots, so a single 8 GB module leaves room for three more upgrades later.

Will the rated 2666 MHz speed run at that frequency once installed in the M720S?

The module operates at 2666 MHz (PC4-21300) with CL19 timings at 1.2 V when the platform supports that speed.
