[Freeware] How to Clear RAM Cache on Windows 11?

About RAM cache memory

Cached RAM, sometimes known as CPU memory, is a type of high-speed Static Random Access Memory. The cached RAM aims to help the CPU perform quicker and more smoothly. Cache RAM is either directly or indirectly linked to the CPU. Cached RAM's job is to store the fundamental instructions and commands that a computer needs often, as well as the data that the CPU is likely to require next. Because the computer can obtain such instructions from Cache faster than from the main memory, it will help to boost the overall performance of the application.

Why do you need clear RAM cache?

When you run a program or a game, Windows will use part of your computer's RAM as a cache so that the same data may be promptly accessed from the RAM cache whenever the application requests it. If the cached memory approaches the limit of your RAM usage, especially when you run too many applications or games simultaneously, you may have difficulties such as abrupt slowing and lag when using the application, out-of-memory errors, or even app or game crashing.

Of course, you can free up RAM by closing apps you don't use. However, when you end an application, Windows does not always erase the cache that the program utilized. The data will remain in the cache so that when you open the same application again, it will start and run faster since the necessary data is still in the cache. Regardless, Windows can recognize when RAM is required for another program and will instantly clear up the unneeded memory cache so that other programs may utilize it.

Thus, users need to clear the RAM cache on the computer to keep RAM status well.
