I assumed this was about sheep at first, and was confused and increasingly concerned.

RAM usually sits at 95% utilized anyway. People who say this dont know the first thing about operatig systems. They cache files…

That currently unused ram has use later on. I don’t use my second ram stick without booting up a game, doesn’t mean it’s a waste.

People also often confuse allocated RAM with used RAM.

Depends on the context, I suppose. I always say to get twice the RAM than you think you need when building/buying a system. Like storage space, the ideal memory usage is 50 percent with the biggest memory eaters you have running. Enough to run everything you have and room to grow for the future.

Or as I prefer to say, no such thing as too much RAM (assuming your system supports it)

I mean it still technically is. Modern web browsers for example use as much memory as they can do for efficiency, but they will free up memory (to certain point) if other applications need it.
