About FerriteCore

FerriteCore reduces how much memory Minecraft uses by storing block states and models more efficiently. The effect grows with the number of mods, so it is common in large packs.

It has no visible effect in game.

Frequently asked questions

Will FerriteCore fix out-of-memory crashes?

It lowers memory use, which can be enough for borderline cases. If a pack truly needs more memory, you still need to allocate more RAM.
