16 GB DDR4 SODIMM kit for Lenovo Legion Y530
This 16 GB kit contains two 8 GB DDR4 2666 MHz SODIMM modules. It is built for Lenovo Legion Y530 and Y730 laptops that use 260-pin DDR4 memory. The CL19 timing and 1.2 V voltage match the platform requirements.
Practical limits of DDR4 2666 SODIMM
The DDR4 2666 standard caps transfer rates at 2666 MT/s with a PC4 21300 bandwidth rating. CL19 latency is fixed by the JEDEC profile for this speed grade. Unbuffered non-ECC modules cannot exceed the two-slot limit of the supported laptops.
Two-slot maximum decides fit
Each supported Legion model provides only two memory sockets with a 16 GB total ceiling. This kit fills both slots to reach that ceiling. Systems needing more than 16 GB or more than two modules cannot use this kit.

Questions about this item
Should I pick the 16GB kit or a single 8GB module for my Lenovo Legion Y530?
The 16GB kit fills both memory slots on the Y530 and Y730 models, giving dual-channel bandwidth and the maximum 16GB capacity those laptops support. A single 8GB stick would leave one slot empty and halve the peak throughput.
What does the DDR4 2666 rating mean once the sticks are installed in a Legion Y730?
The modules will run at 2666 MT/s with CL19 timing at 1.2 V, delivering PC4-21300 bandwidth. If the laptop's memory controller only supports a lower speed, the RAM simply downclocks to match.
Is the 260-pin SODIMM interface on these sticks compatible with the Legion Y530-15ICH slot?
Yes. The 260-pin DDR4 SO-DIMM form factor matches the slot used in the Y530, Y530-15ICH, Y730, Y730-15ICH and Y730-17ICH models listed for this kit.
