How Do I Clear Cached Ram?


In the fast-paced world of technology, a sluggish computer or device can be frustrating. One effective way to boost your system’s performance is by clearing cached RAM. But how do you do it? This comprehensive guide will walk you through everything you need to know about clearing cached RAM, from the basics to advanced techniques.

What is Cached RAM?

Cached RAM, or Random Access Memory, is a crucial component of your device’s performance. It stores data that your computer frequently uses, making it readily accessible. This speeds up operations, allowing your device to run smoothly.

Why Clear Cached RAM?

Clearing cached RAM offers several benefits. It frees up memory space, potentially improving the speed of your device. It can also resolve issues like freezing or lagging applications.

How to Clear Cached RAM

Clearing cached RAM is a straightforward process, and the method varies depending on your operating system. Let’s explore how to do it on different platforms.

Clearing Cached RAM on Windows

For Windows users, follow these steps to clear cached RAM:

Press Ctrl + Shift + Esc to open the Task Manager.

Go to the “Processes” tab.

Select the “Memory” column to sort by memory usage.

Right-click on the processes you want to end and choose “End Task.”

Clearing Cached RAM on macOS

Mac users can clear cached RAM by following these steps:

  1. Press Option + Command + Esc to open the Force Quit Applications window.
  2. Select the applications you want to force quit and click “Force Quit.”

Clearing Cached RAM on Linux

Linux users can clear cached RAM by using the terminal:

  1. Open the terminal.
  2. Type sync && echo 3 | sudo tee /proc/sys/vm/drop_caches and press Enter.

Using Command Line Interface

Advanced users can also clear cached RAM via the command line interface. Simply open the terminal or command prompt and enter the appropriate command for your operating system.

Clearing Cached RAM on Android

Android devices benefit from clearing cached RAM too. Here’s how you can do it:

  1. Go to “Settings.”
  2. Select “Storage.”
  3. Tap on “Cached data” and confirm the clearing process.

Clearing Cached RAM on iOS

iOS users can’t manually clear cached RAM, but restarting the device achieves a similar effect. Simply turn your device off and on again to free up memory.

Common Mistakes to Avoid

While clearing cached RAM is beneficial, there are some common mistakes to avoid:

  • Clearing cached RAM vs. restarting: Understand the difference between the two methods.
  • Can clearing cached RAM harm my device?: Learn about the safety of the process.
  • Will it delete my data?: Clarifications about data loss.
  • Is it necessary on modern devices?: Explore the relevance for newer devices.
  • How long does it take to clear cached RAM?: Managing your time expectations.
  • Can I automate the process?: Tips for automating RAM clearing.

How Often Should You Clear RAM?

The frequency of clearing cached RAM depends on your device’s usage. Regular users may benefit from doing it once a week, while power users may prefer more frequent clearing.

Impact on System Performance

Clearing cached RAM can noticeably improve system performance. It can reduce lag and enhance the responsiveness of your device.

Monitoring RAM Usage

To keep an eye on your system’s RAM usage, you can use various monitoring tools and apps. These tools provide valuable insights into how your RAM is being used.

Advanced Techniques

For power users looking to optimize their RAM usage, advanced techniques such as adjusting virtual memory settings and managing startup programs can make a significant difference.


How do I free up cached memory?

You can free up cached memory by closing unused applications and processes, using system tools like Task Manager (Windows) or Activity Monitor (Mac), or by restarting your device.

How do I clear cached RAM?

You can clear cached RAM on Windows by using the “Clear Standby Memory” tool or by restarting your computer. On Mac, you can use the “Purge” command in Terminal.

Clearing cached RAM vs. restarting:

Clearing cached RAM involves releasing stored data from RAM without a full system restart, while restarting your device completely shuts down and reboots the operating system, which also clears cached data.

Can clearing cached RAM harm my device?

Clearing cached RAM should not harm your device, but it may cause temporarily slower performance as the system rebuilds cache. It’s generally safe and can improve system responsiveness.

Will it delete my data?

Clearing cached RAM does not delete your data or files. It only removes temporarily stored data to free up RAM for better system performance.

Is it necessary on modern devices?

On modern devices with sufficient RAM, manual clearing of cached RAM is often not necessary. The operating system efficiently manages memory, but occasional reboots can help maintain optimal performance.

How long does it take to clear cached RAM?

Clearing cached RAM is usually a quick process, taking only a few seconds to complete.

Can I automate the process?

You can automate the process of clearing cached RAM on some devices by using third-party apps or scripts, but it’s generally not required for most users.


Clearing cached RAM is a simple yet effective way to optimize your device’s performance. It can help you avoid slowdowns, freezes, and other frustrating issues. By following the steps outlined in this guide, you can keep your system running smoothly and efficiently.
