There’s no point in having RAM sit empty - if it’s empty, it’s being wasted. Even if your RAM is completely full and your computer needs more of it to run an application, your computer can instantly discard the cached data from your RAM and use that space for the application. RELATED: Why It's Good That Your Computer's RAM Is FullĬrucially, there’s no point in having RAM empty. When you need the data again, your computer doesn’t have to hit your hard drive - it can just load the files from RAM. Whether it’s copies of web pages you had open in your browser, applications you previously opened, or any other type of data you might need again soon, your computer hangs onto it in its RAM.
Instead, your computer uses your RAM to cache data for faster access. That 3 GB of used RAM doesn’t necessarily indicate waste. In reality, modern operating systems are pretty good at managing memory on their own. That can be surprising to some people - look how bloated modern versions of Windows are! How are you ever going to run additional programs with so little memory available? You may look at your computer’s RAM and see it filling up - for example, you may have 4 GB of RAM and see that 3 GB is full with only 1 GB to spare. Memory optimizers are based on a misunderstanding. Is Your Computer’s RAM Filling Up? That’s Good!
