In reality, modern operating systems are pretty good at managing memory on their own. That 3 GB of used RAM doesn’t necessarily indicate waste. Instead, your computer uses your RAM to cache data for faster access. 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. When you need the data again, your computer doesn’t have to hit your hard drive — it can just load the End
Notice that very little RAM is actually “free” in the screenshot below. The RAM is being used as a cache, but it’s still marked as available for any program that needs to use it.
In the past, full RAM did indicate a problem. If you were running Windows Vista on a computer with half a gig of RAM, you could feel the computer constantly slowing down — it had to constantly read and write to the hard drive, using the hard drive’s page file as an inefficient replacement for RAM. However, modern computers generally have enough RAM for most users. Even low-end computers generally ship with 4GB of RAM, which should be more than enough unless you’re doing intensive gaming, running multiple virtual machines, or editing videos.
Even if RAM was a problem for you, there’s no reason to use a memory optimizer. Memory optimizers are snake oil that are useless at best and harmful at worst.
