When your PC starts to feel sluggish during heavy multitasking, the cause is often physical RAM filling up. Browser tabs, background apps, and old data Windows hasn't released yet all add up. Manually clearing memory works, but you'll need to remember to do it every time.
Wise Memory Optimizer can watch RAM usage for you and clean automatically once it crosses a threshold you set. No clicking, no popups, no interruption to what you're doing. Here's how to set it up.
Steps to Auto-Clean RAM Using Wise Memory Optimizer
Step 1. Install and Launch
Download Wise Memory Optimizer from the official site if you haven't yet. Install it and open the app.
Step 2. Open Settings
Click the Settings icon in the top-right corner.

Step 3. Enable Threshold-Based Cleanup
In the Settings window, look for Auto Optimization. Check the box to enable it. Then select When avalible memory is less than.

Step 4. Set Your Threshold
Drag the slider. 30% is a sensible starting point, high enough that cleanup doesn't kick in too often, low enough to catch real pressure. Adjust later if it fires too aggressively.

Step 5. Optional: Quiet Mode and CPU-Idle Trigger
Two related options are worth a look. Run when CPU is idle runs cleanup only when your CPU is quiet, so it doesn't compete with active workloads. Show notification after optimizing is on by default. Turn it off if you'd rather not see popups.
- Run when CPU is idle: smoother for gaming and video work.
- Show notification after optimizing: leave off for a fully silent experience.

Step 6. Apply
Click OK to save. Wise Memory Optimizer minimizes to the system tray and starts watching.
Conclusion
Once the threshold is set, you don't have to think about it. Wise Memory Optimizer keeps an eye on your RAM and quietly does the work whenever pressure builds. For finer control, the other tools in the same app, like memory defrag and standby release, are worth exploring.
