How to add RAM correctly?

Question

RAM

I have an asus s500ca laptop.
Now it costs 4 GB of RAM (soldered).
I want to add another 8GB. If it makes sense to add 8, or is 4 still better, what would work in two-channel mode?

Answer 1

8 is better, forget about the channel. There, fractions of a percent would increase productivity, you won’t even notice them.
