Learn how to clear RAM cache on Windows 11/10 using 4 easy methods to free up memory, reduce lag, and improve PC performance.
Eleven Wednesday
If your PC is slower to respond to programs, stalls during multiple tasks, or seems slow even when you aren't using heavy software, then you may be dealing with computer slowdowns. One of the common reasons for a slow performance is the high usage of RAM. Over time, the amount of memory available for running programs could be limited by the amount of memory that is being used for caching. Clearing RAM cache can help to free up memory, boost responsiveness and lessen system lag. This guide details how to clear RAM cache manually and automatically, applicable to Windows 11, 10 and previous operating systems.
RAM cache is an area of your computer's memory that temporarily holds files, applications and system information that you have recently used. Windows stores data in RAM for instant access rather than having to load it repeatedly from the SSD or hard drive. This will make applications start quicker and boost system performance.
Windows stores a portion of information in the cached memory when you open a program or file. When content is accessed again, the system reads directly from RAM and skips the reading from the storage. This fastens the loading time and enhances performance.
RAM cache speeds up your computer by storing frequently used data in fast-access memory rather than loading it repeatedly from slower storage drives. This reduces latency, makes apps and web pages load faster, and prevents the system from waiting on slower hardware.
Generally, modern operating systems automatically manage RAM cache, and it is unnecessary to clear RAM cache manually. But If you experience the following symptoms, you might need to clear RAM cache:
Slow application startup
Frequent freezing or lag
Delayed response when switching programs
High memory usage in Task Manager
Browser tabs crashing unexpectedly
Games stuttering during gameplay
"Out of Memory" warnings
Slow file transfers
Reduced multitasking performance
Programs becoming unresponsive
Insufficient RAM probably causes multiple unexpected system issues. You can clear RAM cache on PC to frees up resources that may no longer be needed.
Fix PC Lags: When memory becomes crowded with cached data, Windows has fewer resources available for active applications. Clearing cache can improve responsiveness.
Resolve Software Glitches: Some applications continue using memory even after closing. Removing cached memory can help eliminate these leftover processes.
Reduce Drive Strain: When physical memory runs low, Windows relies more heavily on virtual memory stored on your drive. Freeing RAM reduces this dependency.
Enhance Security: Cached memory may temporarily store information from previously used applications. Clearing it removes unnecessary residual data.
Improve Multitasking: More available RAM allows Windows to allocate resources more effectively across multiple running programs.
The easiest method to clear RAM cache is to restart your computer. Once Windows starts up again, the contents of the active memory is deleted, any processes running in the background are reset and any cached memory is updated. This frequently helps overcome temporary performance problems right away.
Steps to Restart Your PC
Step 1: Click on the Start button on the taskbar and push the Windows Start menu down from the lower left corner of your screen.
Step 2: Click on the Power icon to check the list of power options like Sleep, Shut Down, Restart.
Step 3: Click Restart and let Windows close the programs and automatically restart.
Step 4: Once your PC is back on, open Task Manager and see how much memory is being used to make sure that RAM resources are being refreshed.

Windows can be configured to create a shortcut that will clear some memory caches each time the shortcut is run, so that the computer need not be rebooted. This is a convenient and fast way to clear your Ram cache, which is why it is a favorite among many users who are seeking a way to do so.
Steps to Create a RAM Cache Shortcut
Step 1: Right-click on the blank space of the desktop, pick New, and then pick Shortcut on the menu.
Step 2: Type the following command in the location field and click Next to proceed with creating the shortcut.
%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
Step 3: Enter the shortcut name Clear RAM Cache and click Finish to add this shortcut to desktop.
Step 4: Double click the shortcut whenever memory is being used up to let Windows process idle tasks and refresh memory resources.
Although this doesn't actually remove anything from RAM, it may assist Windows in optimizing RAM usage.

Doesn't clear all cached memory
For more advanced RAM cleaner, the best tool for the job is the Microsoft's RAMMap utility. This is RAMMap, a free tool for memory analysis from Microsoft Sysinternals. It offers comprehensive memory information and users can safely clear standby memory.
Steps to Clear RAM Cache Using RAMMap
Step 1: Download the RAMMap from the Microsoft official Sysinternals website and install or extract the RAMMap on your computer.
Step 2: Right click on the RAMMap application and run it as Administrator to gain access to some more advanced memory management options.
Step 3: When RAMMap appears, click the Empty menu at the top and select Empty Standby List to clear the cached standby memory.
Step 4: Wait a few moments and it is finished, go to Task Manager and view the new RAM usage and available memory.
A lot of cached memory can be used by the Standby List. When it is cleared, it will free RAM immediately.
