Optimize RAM Usage in Microsoft Edge with Resource Controls
Resource Controls in Microsoft Edge is a built-in feature that stops the browser from hogging your computer’s memory. Microsoft Edge runs on the Chromium engine, which delivers fast web browsing but often drains massive amounts of RAM when you open multiple tabs.
Turning on Resource Controls limits how much memory Edge can use at once. This keeps extra RAM free for your games and other desktop programs, so your PC stays fast and responsive.
Optimize Microsoft Edge RAM usage by going to Settings System and performance, then toggling “Resource controls” on. You can then set a RAM limit and choose when it applies, such as during gaming or always. This prevents Edge from consuming excessive memory.
Turn On or Off Resource Controls for Microsoft Edge
Managing how much memory Microsoft Edge uses happens by turning on its resource controls directly in the Performance settings. Limiting the browser’s memory demands helps the computer run smoother.
- Open the Microsoft Edge browser.
- Click the three dots (Alt+F) in the top right corner and select Settings.

- On the left menu, click System and performance.

Under the “Manage your performance” section, controls for Memory Saver and Resource controls appear.
Understanding Memory Saver vs. Efficiency Mode
Microsoft Edge offers two main features to save computer resources and help the browser run faster: Memory Saver and Efficiency Mode. Memory Saver frees up memory from unused tabs, while Efficiency Mode focuses on reducing background activity.
- 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
Setting a specific limit for how much RAM Microsoft Edge is allowed to use prevents the browser from taking over system memory. 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.
- 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.

Setting a limit allows the browser to operate normally until it reaches that cap. Once hit, Edge sleeps or discards older tabs to stay within the chosen limit.
Enable or disable Resource controls using Windows Registry Editor
Advanced setups require the Windows Registry Editor to manage resource controls system-wide. This involves navigating to a specific path and creating a new DWORD value named MemorySaverEnabled.
- Open the Windows Registry editor as an administrator.
- Go to this path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge
- Right-click in the right pane, select New > DWORD (32-bit) Value.
- Name it MemorySaverEnabled.
- Double-click it and set the value to 0 to disable the feature for everyone on the computer.

Restarting the computer helps these changes take effect.

Conclusion
Balancing browser speed with system stability happens through these settings. Combining AI-driven Memory Saver with manual RAM limits ensures Microsoft Edge stays fast without slowing down other important tasks.
How to stop Microsoft Edge from taking up RAM?
Wondering how to stop Microsoft Edge from using so much RAM? Look for settings like hardware acceleration, background mode, startup boost, and proxy settings. Click on 'System' – 'Startup boost' appears there. Turning off this feature helps reduce resource usage.
Does Edge have a RAM limiter?
Wondering if Edge features a dedicated RAM limiter? The tool lets you cap memory consumption specifically during gaming sessions or permanently. Setting the rule to 'Always' covers constant usage, and the slider determines exact RAM allocation.
