The laptop I bought for college (laptop is going to be used for school work and general web browsing no gaming or anything) only came with 4GB of RAM I want to get a single 8GB stick of RAM to upgrade to but I don't know if I should get DDR4 or DDR3. And also any RAM that you might reccomend please feel free to post them, I have never bought laptop RAM before only desktop. (other wise I will probably buy the top results on amazon which are made by Crucial)
