Virtual RAM is the one typically stored in a file in your system drive it’s called pagefile.sys in Windows and swapfile in Mac OS X. On the other hand, hard drive storage is very slow, so the passive processes are moved there to keep more RAM free to tackle more important or pressing processes. Physical RAM is high-speed, so all active processes are written there. Operating systems use both the RAM and storage inside your hard drive to write and exchange processes.Īlmost all the latest operating systems (released in the last ten years) have a smart RAM management system to cache processes and take full advantage of the physical RAM and the virtual RAM stored in the hard drive storage. In this article, I will try to clear up misconceptions about RAM cleaning tools. Well, there are loads of debates going on around RAM cleaning/optimizing tools, both in favor and against. Have you ever wondered how the cleaning and quickly boosts in RAM work? How do these tools free up RAM? Do they allocate the processes somewhere else or kill the processes? Or do they just fake it? If you don’t have 'enough' RAM in your PC, then you must have tried (or thought of trying) a RAM cleaning tool that promises to quickly 'free up' RAM.
