According to, the memory in both the i7 and i5 processor versions of the 2015 Macbook Air cannot be upgraded post-purchase, and according to, could be upgraded to 8gb maximum. The “procedure” of upgrading at time of purchase is simply having Apple either go to the back room and get you a computer with more RAM, or replace the logic board. But I’m guessing you were asking about a component level procedure like the one discussed by IBoff Mat on his Facebook or Youtube channel. IBoff Mat (in Malaysia) says he has successfully upgraded these machines to 16 gb. This teardown document here on iFixit only talks about a 4gb machine, but has part numbers on it. I’m in the process of looking for other people’s videos or documentation on this myself. Sorry I don’t have more information yet, but when I do, I’ll post it here.

Replacing the RAM chips is not a trivial process!

It requires someone with very good micro-soldering skills, clearly not a DIY job. Best just replace the full logic board if you want to get it to 16GB and that's the highest it can be installed.
