Ever noticed your computer slowing down even when you’re not running many programs? One common cause is the build-up of RAM cache — memory that’s reserved by the system or applications but not actively used. This cache can take up space and reduce available RAM for other tasks.
Fortunately, you can clear the RAM cache without restarting your computer by using a free tool from Microsoft called RAMMap v1.61.
What is RAMMap v1.61?
RAMMap v1.61 is a free utility from Microsoft Sysinternals that allows users to analyze how Windows uses physical memory (RAM) in great detail. In addition to analysis, RAMMap includes a powerful feature to clear RAM cache, helping you free up memory and improve your PC’s performance.
