There's no relation between the CPU and amount of RAM. The amount of RAM you need is dependent on what you do with the laptop. So your question is a rather strange one.
Adding 4 GB RAM doesn't seem a bad idea.
So. I have this new laptop from Asus the Asus x542u that has a core i5 8th Gen in it with 4Gb of DDR4 ram and I've noticed that whenever I multi task like premiere pro and google chrome at the same time my laptop kind off hangs for a couple of second before it switch in between apps. or could it be just the google chrome because even f I don't multitask google chrome still hangs on me for a couple of seconds and its infruriating when I do some of my work.
I'm actually planning to buy a 4gb upgrade so it would help me a lot if you can give me some answers before I do. Thank You in advance
