Lenovo ThinkCentre M720S upgrade kit

This 32 GB kit contains four 8 GB DDR4 modules built for Lenovo ThinkCentre M720S SFF and Tower systems. It is intended for owners of those specific desktops who need to reach the platform maximum of 64 GB across the four available slots. Buyers with other motherboards or laptops cannot use this memory because the pin layout and timing are tuned for the listed models only.

DDR4 2666 CL19 unbuffered specification

Each stick runs at 2666 MHz with a CAS latency of 19 and operates at the standard 1.2 V for DDR4. The modules are non-ECC, unbuffered and organised as dual-rank 2Rx8, matching the exact electrical requirements of the ThinkCentre M720S platform. Systems that require ECC, registered DIMMs or a different voltage will not accept this kit.

Four-module pack with lifetime exchange

The package delivers four separate 288-pin DIMMs so all four slots can be populated in a single step. Computer Memory Solutions backs the kit with a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly from them. No software, heat spreaders or additional accessories are included.

Questions about this item

What does the 2666 MHz speed mean once the kit is installed in a ThinkCentre M720S?

The modules run at 2666 MHz with CL19 timing at 1.2 V, delivering the rated DDR4 21300 bandwidth inside the M720S SFF or Tower.

How does the 288-pin DDR4 interface limit performance in this system?

The 288-pin DDR4 DIMM slots on the M720S accept these unbuffered non-ECC sticks at their native 2666 MHz; no higher speed is supported by the platform.

What physical clearance is needed to fit the four 8 GB sticks in the M720S SFF?

Each stick is a standard-height 288-pin DIMM without a heat spreader, so all four populate the four slots in the SFF chassis without clearance issues.
