Optimize RAM Usage in Microsoft Edge with Resource Controls

Turn On or Off Resource Controls for Microsoft Edge

You can manage how much memory Edge uses directly in the browser settings. The path is the main menu, then Settings, then the System and performance page. You don’t need administrator rights for this method, and the changes apply only to your own Edge profile.

If a setting described below is missing, update Edge first and check again. Edge normally updates itself, but it only installs the update after a restart of the browser.

1. Open the Microsoft Edge browser.
2. Click the three dots in the top right corner (or press Alt+F) and select Settings. The Edge Settings page opens in a new tab.

1. On the left menu, click System and performance. If you don’t see the left menu, the window may be too narrow. Widen it, or click the menu icon at the top left of the Settings ⚙️ page.

Under the “Manage your performance” section, you should now see the controls for Memory Saver and Resource controls. If Resource controls is missing, your Edge version probably doesn’t include it yet. Update Edge and restart it, then look again.

Understanding Memory Saver vs. Efficiency Mode

Memory Saver and Efficiency Mode are the two main Edge controls for saving system resources. Memory Saver frees up memory from inactive background tabs. Efficiency Mode reduces overall browser activity to save power and keep your system responsive during heavy use. They do different jobs, and you can use them together.

• Memory SaverThis 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. When you go back to a tab that was put to sleep, it may reload, so unsaved form data on that page can be lost. Pick Balanced if that bothers you.
• Efficiency ModeThis 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. On a desktop PC you may notice little difference. On a laptop running on battery, it matters more.

Setting Your RAM Limits

Setting a specific RAM limit stops Edge from taking over your system memory when you run heavy apps or games. You turn on Resource controls, choose when the limit applies, and use the slider to set the maximum amount of RAM Edge may use.

1. Under “Manage your performance”, turn the Resource controls switch to On. The related options appear below it.
2. Choose when the limit applies: Only during PC gaming or Always. Pick Always if other heavy programs, not just games, compete with Edge for memory.
3. Move the slider to pick the maximum amount of available system RAM (memory) Edge can use. Don’t set it too low. A very small cap makes Edge discard tabs constantly, and pages will keep reloading.

To undo this, turn the Resource controls switch back to Off. No restart is needed.

Once it hits the cap, Edge puts older tabs to sleep or discards them to stay within the limit. The tabs stay in your tab bar, and the page reloads when you click it. If you see this happening often, raise the slider a little.

Enable or disable Resource controls using Windows Registry Editor

You can also use the Windows Registry Editor, a database of system configuration settings, to apply these features system-wide for every user on the PC. This is an advanced method. You open the registry as an administrator, go to the Edge policy path, and create a DWORD value. It works on both Windows 11 Home and Pro. Back up the registry or create a restore point before you change it, because a wrong edit can cause problems.

1. Open the Windows Registry editor as an administrator. Right-click it and choose Run as administrator, then click Yes if User Account Control asks for permission.
2. Go to this path: Computer\🗝️HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edgecopy. If the Edge key doesn’t exist, right-click the Microsoft key, select New › Key, and name it Edge.
3. Right-click in the right pane, select New › DWORD (32-bit) Value. A new entry appears with its name ready to edit.
4. Name it MemorySaverEnabled.
5. Double-click it and set the value to 0 to disable the feature for everyone on the computer. Click OK.

To undo this, delete the MemorySaverEnabled value you created. Edge then goes back to using each person’s own settings.

Restarting the computer helps these changes take effect. This matters most for the registry method, since policies are read when Edge starts. At the very least, close all Edge windows and open the browser again.

Conclusion

These settings let you balance browser speed against system stability. Memory Saver handles inactive tabs on its own, and a manual RAM limit adds a hard cap on top of it. Used together, they keep Edge fast without slowing down your other important tasks. If something feels off, such as tabs reloading too often, loosen the limit or switch Memory Saver to Balanced.
