I’ve recently upgraded my Lenovo Y720 RAM to 64GB. This laptop came with 16GB initially, but it’s very easy to upgrade it.
I was browsing Amazon and found that the Samsung 32GB DDR4 SODIMM modules were the cheapest available, so I went ahead and ordered 2 of them.
Upgrading it was as easy as removing the back cover:

Here we insert them in the laptop:

The most important thing is that now my laptop has 64GB of RAM which will be plenty for a very long time.
