I would like to get the model number and URL link to brand new 8 GB memory modules from Kingston or Samsung that are guaranteed to work in the Lenovo W520-4284.

It is my understanding that it is recommended to take 1.5V modules to avoid the risk of overheating when 1.35V modules incorrectly run at 1.5V, if the BIOS contains an older version.

The modules should be brand new, and if possible the URL link should point to an official and reputable web shop in Europe.

Would this 8 Gb module from Hynix work?

Can it do PC3 only? And not PC3L?

Can't help you with the model, but W520 needs any DDR3-1333 to 1600 (PC3-10600 to 12800) SODIMMs running at 1.5V
The PC3L/DDR3L at 1.35V run too hot, do NOT use those!
