This question already has an answer here:
My laptop is Thinkpad T400, and running 64 bit Ubuntu 14.04. I wonder if there is no limit of the RAM size that I can use in my laptop?
Now I am running Windows 8.1 in VirtualBox, which takes 2GB RAM, and if I open 80 Chrome tabs, My RAM (8GB, which is two 4GB RAM cards occupying two slots in the laptop, I am not sure if there are extra slots) will be fully used, and my swap (16GB) will be half full, and the speed is slow because of constant swapping.
I am thinking about upgrade my RAM to a bigger size (maybe 32GB or more). But not sure if there is some limitations on the RAM size, how many RAM cards I could buy and insert into the laptop, and other aspects that I should be aware of. So I appreciate your reply!
