Optimize RAM Usage in Microsoft Edge with Resource Controls

You can optimize RAM usage in Microsoft Edge by using its built-in Resource Controls feature to manage memory allocation for your browser.

Resource Controls allow you to set specific limits on how much RAM Microsoft Edge consumes, ensuring your PC remains responsive even when running demanding applications or games.

This feature is especially useful since Microsoft Edge, built on the Chromium engine, can sometimes be a significant memory user, alongside its evolving AI-driven performance enhancements like sleeping inactive tabs.

By manually adjusting these settings, you gain direct control over memory usage, potentially freeing up RAM for other tasks. For instance, you can choose to prioritize performance or limit Edge’s footprint on your system.

Turn On or Off Resource Controls for Microsoft Edge

You can manage how Edge uses memory through the Performance menu. Here is how to find these settings:

1. Open the Microsoft Edge browser.
2. Click the three dots (Alt+F) in the top right corner and select Settings.

1. On the left menu, click System and performance.

Under the “Manage your performance” section, you will see controls for Memory Saver and Resource controls.

Understanding Memory Saver vs. Efficiency Mode

These two features work together to keep your PC fast:

• Memory Saver: This mode frees up memory from inactive tabs. You can choose Balanced, which saves memory while keeping your current tabs responsive, or Efficiency, which is more aggressive and prioritizes saving resources above all else.
• Efficiency Mode: This is a broader setting that helps optimize your PC’s power usage and battery life while Edge is running. It works in tandem with Memory Saver to ensure the browser does not hog resources while you are multitasking.

Setting Your RAM Limits

In the same menu, you can set a hard limit for RAM usage:

• Toggle the Resource controls switch to On.
• Choose when the limit applies: Only during PC gaming or Always.
• Adjust the slider to pick the maximum amount of available system RAM (memory) Edge can use.

When you set a limit, the browser works normally until it hits that cap. Once reached, Edge will sleep or discard older tabs to stay within your chosen limit.

Enable or disable Resource controls using Windows Registry Editor

Advanced users can manage these settings for the whole system using the Registry Editor. Note that as of 2026, the policy key MemorySaverEnabled has replaced older keys like RAMResourceControlsEnabled in the latest Administrative Templates.

1. Open the Windows Registry editor as an administrator.
2. Go to this path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge
3. Right-click in the right pane, select New > DWORD (32-bit) Value.
4. Name it MemorySaverEnabled.
5. Double-click it and set the value to 0 to disable the feature for everyone on the computer.

You may need to restart your computer for these changes to take effect.

Conclusion

Using these settings allows you to balance browser speed with system stability. By combining the AI-driven Memory Saver with manual RAM limits, you can ensure Microsoft Edge stays fast without slowing down your other important tasks.
