Need help chosing RAM

[bdawgg]

Hello, I want to add one more 8 Gb ram module for dual channel but I don't know what to choose. My laptop model is Lenovo Legion Y520-15IKBN 80WK00Y9RI. I have this installed from factory: 8Gb Ramaxel RAMRMSA3260MH78HAF-2666 and I need one more for proper dual channel but I can't find any Ramaxel in my country. Also, I looked up for specifications on my laptop's manufacturer website and it says it only supports 2400Mhz so why does it really have 2666MHz installed ? 

Here are some informations from CPUZ:

Thank you!

Installed stick supports up to 2666, but it is running at 2400 (CPU-Z, Memory Tab, Timings section, DRAM Frequency).

 

Finding same memory is hard, especially since Ramaxel isn't very known manufacturer. What you can try is finding memory with same (or as similar as possible) capacity, frequency and timings. Some laptops are very picky about memory, so you'll have to hope for the best.

pc4-21300 8gb sodimm - use that as a search term on newegg, amazon, or ebay.  you shouldn't need to spend more than $30 - USD plus tax and shipping

 

it DDR4 - 2666 megahertz SoDIMM is important as desktop RaM isnt gonna fit in your laptop
