Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Mekanism Overflow Energy

No more frustration with energy transfer bottlenecks in mekanism.

Mekanism Overflow Energy allows mekanism to transfer energy beyond INT_MAX(≒2.14*10⁹).

Details

By default, Mekanism is limited by the ForgeCapabilities.ENERGY system, which caps a single energy transfer at Integer.MAX_VALUE (~2.14G FE).

Mekanism Overflow Energy extends this limit by transferring Integer.MAX_VALUE multiple times per tick, allowing up to Integer.MAX_VALUE * maxOperationCount energy to be transferred per tick.

Configuration

A config file is generated at:

config/mekanismoverflowenergy-common.toml

maxOperationCount - the maximum number of repeated transfers (default: 256)

Be careful, as setting the number of times too high will significantly reduce TPS.
