What is a RAM Cleaner?

Do you know what the RAM on your computer is used for?

When you open a program or website, it’s stored in your RAM. So if your RAM is full of unnecessary data, it can cause your computer to run slowly. That’s where a RAM cleaner comes in: It clears out the unnecessary data and makes more space for new data. This will allow your computer to run at normal speeds again- somewhat as defragging does for the hard drive on your computer.

Why Should You Use One?

You should use a RAM cleaner for various reasons.

During the normal and proper operation of a computer, temporary files are stored in random access memory (RAM). This is only supposed to happen while that program or window is open. Once you close it, then those temporary files should be deleted by your computer automatically. But if something goes wrong and you turn off your computer without properly closing the programs, files, or windows, then those temporary files are not deleted. This can cause your computer to run slow and eventually crash. A RAM cleaner will free up space in your RAM to prevent this from happening.

Not only that, but the longtime use of a computer will lead to performance degradation where the machine starts taking longer and longer to boot up, programs start crashing, and the overall performance drops. This is called “computer aging” or “hard disk aging.” RAM cleaners can prevent this from happening by freeing up space in your RAM every time you run them.

What to Look for When getting a RAM Cleaner?

When getting a RAM cleaner, you want to find one that has high user ratings, free of charge (preferably), and can be used multiple times.

User Ratings

User ratings are important because you want to find one that works well for most people or is liked by most people. You don’t want to get stuck with a RAM cleaner that doesn’t work well for you or is not liked by anyone.


You don’t want to spend a lot when getting a RAM cleaner because so many offer good service for a lesser price or even free. Free RAM cleaners tend to have more user ratings too, which is an advantage in this case.

Can be Used Multiple Times

You should go for a RAM cleaner that can be used multiple times to free up space in your RAM to speed up your computer. You don’t want one that says it can be used X amount of times and then will not work anymore- you’ll end up having to buy a new subscription.

Ease of Use

Nobody wants to get a program that is super hard to use or takes forever to set up. You want something; you can just download and run it once. They should be easy to use so the average person can get good results without having any issues or problems.

Available Support

If you have any problems using the cleaner, be sure to find one with good customer support. This will ensure that you can get help when you need it.

  1. This entire article is deceptive at best. “RAM” cleaners, like most “registry cleaners” are crap-ware. I cannot believe you are pushing this. The BEST ram cleaner is a simple RESTART!! As opposed to a shut-down (which on some machines uses a “fast start-up” option, which stores some ram data on a chip located on the motherboard), a restart clears out all ram. If you feel I am mistaken, please explain to me how ram (volatile) can hold data when there is no voltage going to the chips?? I read that some ram doesn’t always clear in time during a restart, but then you can simply run memtest86 which will clear the ram during the test. No need to bog down your PC with questionable bloatware. This article strikes me as nothing more than an ad for the above mentioned software. Most of your articles are spot on, but this one leaves me very disappointed…
