What this kit is and who it fits

This 32GB kit contains two 16GB DDR4 2666 CL19 SO-DIMM modules built for Lenovo Legion Y545, Y545 PG0, Y7000, Y7000P and Y7000 2019 PG0 laptops. It is intended for owners of those specific models who want to reach the platform maximum of 32GB across two slots.

Practical limits of the DDR4 2666 SO-DIMM standard

The system will run all installed memory at the speed of the slowest module or the processor ceiling, whichever is lower. A 64-bit operating system is required to address more than 4GB. The kit is non-ECC, unbuffered, 1.2V and uses 260-pin layout, so it cannot be used in desktops or servers that expect registered or ECC memory.

Installation notes and common pitfalls

Installation is a matter of opening the laptop service hatch, aligning the notch on each 260-pin stick and pressing firmly until the side clips lock. The most frequent issue is seating a module at an angle so only one clip engages, which leaves the system seeing only 16GB. Mixing these sticks with existing memory of a different speed or timing will force the whole array to run at the slowest common settings.

Questions about this item

Should I choose the 32 GB (2 x 16 GB) kit or a single 16 GB module?

The 32 GB kit provides two matched 16 GB modules for dual-channel operation, while a single 16 GB module runs in single-channel mode and halves total capacity.

What does the 2666 MHz rating mean once the memory is installed in my Lenovo Legion laptop?

The modules will run at 2666 MHz if the processor and chipset support that speed; otherwise they downclock to the highest speed the platform allows.

Is the 260-pin DDR4 SO-DIMM interface compatible with my Legion Y545 or Y7000 series?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the memory slots in Legion Y545, Y545 PG0, Y7000, Y7000P and Y7000 2019 PG0 models.
