Targeted DDR4 SODIMM kit

This 16 GB kit contains two 8 GB unbuffered non‑ECC SO‑DIMMs built to the DDR4 2666 standard. It is aimed at owners of the listed Lenovo ThinkCentre Tiny desktops who want to reach the platform ceiling without compatibility guesswork.

DDR4 2666 bandwidth ceiling

The modules run at 2666 MT/s with CL19 timings and 1.2 V, matching the PC4‑21300 specification the supported systems expect. Performance cannot exceed the memory controller limit of those platforms, so tighter timings or higher frequencies would not be usable even if installed.

Slot count and maximum capacity

Each supported Tiny model provides two SODIMM sockets and a 32 GB total limit. Verify that both slots are free or that you are replacing the existing pair, because a single 8 GB stick already fitted would leave only one slot for this two‑stick kit.

Questions about this item

Should I choose the 16GB (2 x 8GB) kit or a single 16GB module for my ThinkCentre M720 Tiny?

The 16GB kit provides two 8GB modules to fill both SODIMM slots in the M720 Tiny, enabling dual-channel bandwidth. A single 16GB stick would leave one slot empty and halve the memory throughput.

What does the DDR4 2666 (PC4 21300) speed rating deliver in daily use on the M715q Tiny (2nd Gen)?

The 2666 MT/s data rate matches the maximum supported memory speed of the M715q Tiny (2nd Gen), so the system runs at full JEDEC frequency without downclocking, giving the best integrated-graphics and multitasking performance the platform allows.

Does the 260-pin DDR4 SO-DIMM interface limit the upgrade to 32GB total in these Lenovo Tiny systems?

Yes, each ThinkCentre Tiny model listed has two 260-pin DDR4 SO-DIMM slots and a 32GB maximum capacity, so this 16GB kit uses half the slots and half the supported memory ceiling.
