Compatible upgrade for Lenovo Legion Y530 and Y730

This 16 GB DDR4 2666 MHz SODIMM module is built for Lenovo Legion Y530-15ICH, Y530, Y730, Y730-15ICH and Y730-17ICH laptops. It uses a 260-pin unbuffered non-ECC design with CL19 timings. The single stick format suits owners filling one empty slot or replacing a smaller module. Buyers needing 32 GB total capacity must purchase two sticks.

Sustained workload behaviour

The module runs at 1.2 V with 2Rx8 organisation and major-brand chips rated for PC4 21300 bandwidth. Under continuous load the memory operates at the lowest common speed of all installed modules and the processor capability. Mixed kits will therefore drop to the slowest timing present. A 64-bit operating system is required to address the full 16 GB capacity.

Physical design and daily use

No heat spreader is fitted so the stick sits low under tight laptop covers. The 260-pin edge connector matches the factory SODIMM socket exactly. Computer Memory Solutions manufactures the module rather than rebranding generic parts and backs it with a limited lifetime warranty against manufacturing defects. System maximum is 32 GB across two sockets.

Questions about this item

Does the 1.2V DDR4 module run hot or loud during all-day use?

The SODIMM operates at 1.2V with no heat spreader and has no moving parts, so it adds negligible heat and makes no noise inside the Legion Y530 or Y730.

What must my laptop already have for this 260-pin stick to work?

Your Lenovo Legion Y530 or Y730 needs a free DDR4 SO-DIMM slot and a 64-bit operating system to address the full 16GB capacity.

Will this CL19 2666MHz module slow down if I keep the original memory in the second socket?

Yes — all installed memory will run at the slowest module's speed and timing, so mixing with slower original RAM reduces overall performance.
