Will RAM help my pc?

[TWTgames]

I have 8GB of RAM right now in my computer, but I would like to have 16GB RAM. I'm looking at a KINGSTON VALUERAM 16 GB SODIMM DDR4-2133. Is this a good RAM? I'm not good at computer part details, so that's why I'm on this site. If I would order the RAM, I'll let a PC business place (I don't know how to call it) settle it in my computer. Hope you guys can help!

Are you using all your RAM currently?
If no, then new RAM is pointless.

Most games don't even use 16. A good 16GB RAM would be Corsair Vengeance LPX.
