Optimize RAM Usage in Microsoft Edge with Resource Controls

This guide explains how to manage your computer’s memory while using Microsoft Edge. Why do this? Controlling how much RAM your browser uses helps keep your computer running smoothly, especially when you are running heavy apps or games.

Microsoft Edge is the default browser for Windows 11 and 12. However, users can  switch to their preferred or favorite browser if they prefer. Edge is built on the Chromium engine, which is the same technology used by Google Chrome.

By 2026, Microsoft Edge includes smart AI features that monitor your performance. The browser uses AI to “sleep” inactive tabs automatically, saving memory without you needing to lift a finger. These manual resource controls work alongside that AI to give you more power over your system.

What happens when you are done? Your computer will have more available memory, which can lead to faster performance in other apps, though setting limits too low might cause your browser tabs to reload more often.

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.
