To clear RAM on a Chromebook, close unused browser tabs and end memory-hungry processes in the Task Manager. Chrome OS is designed to use available RAM efficiently, so high memory usage alone isn't a problem, but if your Chromebook feels slow, these steps will free up memory and restore performance.
Why your Chromebook might feel slow (and how to clear RAM)
Chrome OS, like other Linux-based systems, manages RAM by using available memory rather than keeping it free. This means high RAM usage doesn't necessarily indicate a problem unless you actually notice performance issues like lag, freezing, or slow response times. When those symptoms appear, the solution is to free up memory by closing tabs, ending processes, and disabling unnecessary features. The methods below target the most common causes of slowdowns, starting with the simplest and moving to more advanced options.

Close unused browser tabs
Each open tab consumes memory, even if it's not actively being used. Closing unused tabs is the quickest way to free up RAM and speed up your Chromebook. To close a tab, click the X on the tab itself, or right-click the tab and select "Close Tab." You can also press Ctrl+W to close the active tab. Make a habit of periodically reviewing your open tabs and closing any you no longer need, this alone can often resolve sluggishness.
End processes with the Task Manager
When closing tabs isn't enough, the Task Manager lets you see exactly which processes are using the most memory and end them. To open it, press Shift+Esc, or click the three-dot menu in Chrome, go to "More Tools," and select "Task Manager." The list shows each process and its memory usage, sorted from highest to lowest. To close a memory-intensive process, select it and click "End Process." Be aware that ending a process can cause data loss if you have unsaved work open in that application, so save your work first.
Disable or remove unnecessary extensions
Every Chrome extension, even inactive ones, uses RAM and CPU. To check your extensions, click the three-dot menu, go to "More Tools," and select "Extensions." From there, you can disable any extension you don't use regularly by toggling it off, or remove it entirely by clicking "Remove." If you want to allocate more RAM to TModLoader, disabling unused extensions can free up memory for that purpose. Reducing your extension load can noticeably improve overall system responsiveness.
Disable the Android or Linux environment
The Android subsystem (Google Play Store) can consume approximately 1 GB of RAM, and Linux containers also increase memory demand. If you don't actively use Android apps or Linux development tools, turning them off can reclaim significant memory. Go to Settings, then "Apps," and turn off "Google Play Store." For Linux, go to Settings, then "Developers," and toggle off "Linux development environment." This frees up RAM that those subsystems were reserving, but if you need more memory for Android apps you can't remove, you might increase RAM on a tablet instead.
Restart your Chromebook regularly
A simple restart clears cached memory and resets background processes that may be consuming resources. To restart, click the system tray in the bottom-right corner, select the power icon, and choose "Restart." For best results, restart your Chromebook at least once a week. This prevents gradual memory buildup from long uptime and ensures your device starts fresh.
Powerwash your Chromebook as a last resort
If performance issues persist after trying all other methods, a Powerwash (factory reset) can restore your Chromebook to its original state. This removes all data, apps, and settings, so back up important files to an external drive or cloud storage first. To Powerwash, go to Settings, click "Advanced," then under "Reset settings," select "Powerwash" and follow the prompts. Use this only when other steps have failed, as it requires setting up your Chromebook from scratch afterward.
