5 Best RAM Cleaners for Windows PC

Do you miss those times when your computer was fast, smoothly functioning, and you could juggle between applications as much as you wanted? If you wonder where those days have gone, it is wise to check whether your Windows PC’s RAM is cluttered, and if so, use a RAM cleaner to give it the much-needed breathing space to bring back the lost smooth, snappy performance.

Cluttered RAM —i.e., if the RAM is near or at full capacity —may force your operating system to rely excessively on virtual memory (also known as the paging file) on the storage drive (HDD or SSD), leading to significant performance degradation. 

To check if your RAM is cluttered, i.e., your RAM usage consistently ranges between 85-100%, you can follow the path Ctrl+Shift+Esc>Performance>Memory to see the current percentage of RAM being used. 

If you find the RAM usage concerning, i.e., 85-100%, you can use one of the best RAM cleaners for Windows 10/11 reviewed in this article, including software such as Wise Memory Optimizer, Fortect, IOLO System Mechanic, Razer Cortex, and IObit Advanced SystemCare. 

However, before going deeper into the best PC RAM cleaners, let’s clear any confusion you may have about what exactly a RAM cleaner is and why you need one in the first place. 

What Is a RAM Cleaner

Simply put, a RAM cleaner is a software that frees up a PC’s random-access memory (RAM) by closing inactive processes and programs, and clearing the memory and cache. 

While modern Windows systems (Windows 11 and 10) have a built-in memory management system, third-party RAM cleaners, also known as RAM optimizers and boosters, offer added advantages, such as more efficient real-time RAM consumption viewing, boosting CPU performance, and enhancing the system’s memory by killing unwanted processes. 

Hence, performing a memory or cache clearing action using the best RAM cleaning software is an excellent way to fix application malfunctions, free up resources for specific tasks, and clear corrupted cache that may degrade your system performance. 

Now that you are familiar with RAM cleaners and what they do, let’s help you choose one for your computer.
