Fix Random Freezes and Memory Issues

Understand Auto-RAM Cleaner

The mod includes an automatic memory management system that runs in the background. The Auto-RAM Cleaner clears unused memory every five minutes to prevent your game from freezing during long play sessions.

What Causes Freezes

Minecraft can freeze when your computer's RAM fills up, especially during storms with many particles or in large loaded areas. This mod reduces those freezes by cleaning memory automatically without you doing anything.

Optimize Further

If you still experience occasional freezes:

  • Switch to Super Fast mode, which is most aggressive with memory management
  • The Far Particle Deletion feature removes distant visual effects during storms and fights, reducing memory strain
  • Avoid loading extremely large areas at once

Monitor Performance

Open the debug screen (F3) to watch your memory usage. If freezes persist, try closing other programs running on your computer to free up system RAM. The mod works best when your computer has adequate total memory available.
