So basically I want to upgrade My (AN515-57-5700) Acer Nitro 5’s RAM (originally 16GB) (2 slots for RAM) and also add a secondary NVMe SSD. But one issue is I did some research and apparently some have said my model only goes up to 32GB, and another source says up to 64GB. So I’m not sure which to buy, whether 2x32GB RAM to equal 64 or one more 16GB to equal 32 RAM

And also regarding the NVMe slot, I don’t know the maximum storage capacity of the second slot. So I’m not sure whether I should buy a 1TB, 2TB or 4TB m2 for it. Again I have researched and I couldn’t find an exact answer. Any help/suggestions???
