Less stutter. Fewer freeze spikes. Better long-session stability.
Why Players Install MemGuard
- Stabilizes memory usage in big modpacks and long play sessions.
- Cuts duplicate NBT string allocations to reduce RAM pressure.
- Adds memory warnings before your session becomes unstable.
- Runs safely with standard loader/JVM APIs (no native hooks).

Compatibility Notes
- Known good with FerriteCore and AllTheLeaks.
- If logs mention missing Create classes, verify Create and Create addons are on the same update line (Update 5 with Update 5 addons, or Update 6 with Update 6 addons).
- That Create class mismatch is usually not caused by MemGuard itself.
Quick Install
- Install the correct loader for your Minecraft version.
- Use Java 21+.
- Put
MemGuard.jar in your mods folder.
- Start the game and check
latest.log for [MemGuard] entries.
Build smoother modpacks, not restart loops.
Use MemGuard when your world is big and your sessions are long.
