Okay, so, this is probably a stupid question but I am not very familiar with computers, but i'm trying to get more RAM and I know that you need to put both sticks into the same color, but do they have to be the exact same? My computers uses DDR4 ram and I have a pre-built gaming PC with one stick of XPG 8 gigabyte ram. Now, I would just buy another one of those but unfortunately, that company only sells theirs in pairs, and I only need one 8 gigabyte stick. So, would it matter if I bought another stick from a different company? Again, i'm sure this is very stupid but I am unfamiliar with computers and don't wanna waste my money.
