What are the main criteria for selecting "good" RAM? Obviously, everyone wants quantity with RAM, 16GB is better than 8GB, but what about quality? What are the main factors involved? When I see two RAM sticks, each with the same quantity of RAM, at two different price points, how should I determine what to get?
Is there such a thing as RAM speed, and does it make a significant difference which makes a disparity in price justifiable?
