RELATED: PC Cleaning Apps are a Scam: Here's Why (and How to Speed Up Your PC) This makes no sense! All it accomplishes is selling you another system optimization program you donвЂ™t need.

In other words, these programs free up fast memory by forcing data you need onto slower memory, where it will have to be moved back to fast memory again.

Any memory being used for cache may be discarded, so Windows will have to get the data it needs from the hard drive. However, all this does is slow things down - now the applications you use will have to get the data they need from the page file, reading from the hard drive and taking longer to work.

They then deallocate the memory, leaving it empty.Д«oth of these tricks will indeed free up RAM, making it empty.

They quickly allocate a large amount of memory to themselves, forcing Windows to discard cached data and write application data to the page file.

They call the EmptyWorkingSet Windows API function, forcing running applications to write their working memory to the Windows page file.

Memory optimizers actually work in one of two ways: This may seem like an easy win - youвЂ™ve decreased RAM usage just be pressing a button, after all.

When you use a memory optimizer, youвЂ™ll see your computerвЂ™s RAM usage go down. Memory optimizers are snake oil that are useless at best and harmful at worst. Even low-end computers generally ship with 4GB of RAM, which should be more than enough unless youвЂ™re doing intensive gaming, running multiple virtual machines, or editing videos.Д®ven if RAM was a problem for you, thereвЂ™s no reason to use a memory optimizer. However, modern computers generally have enough RAM for most users. 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 driveвЂ™s page file as an inefficient replacement for RAM.

In the past, full RAM did indicate a problem. The RAM is being used as a cache, but itвЂ™s still marked as available for any program that needs to use it. Notice that very little RAM is actually вЂњfreeвЂќ in the screenshot below. If itвЂ™s full, thereвЂ™s a good chance it can help speed up program loading times and anything else that would use your computerвЂ™s hard drive. ThereвЂ™s no point in having RAM sit empty - if itвЂ™s empty, itвЂ™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.

When you need the data again, your computer doesnвЂ™t have to hit your hard drive - it can just load the files from RAM. Whether itвЂ™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 doesnвЂ™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 computerвЂ™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 ComputerвЂ™s RAM Filling Up? ThatвЂ™s Good!
