By default, Minecraft starts up with only 1GB of memory to work with. While Pixelmon generally does run with the default allocation, allocating more is advised for performance and stability. This is especially true when also running other mods. This quick guide will guide you through the process.

Stuck on 1GB? A 64 bit install of Java is required to be able to allocate more than 1GB of memory. You can get a 64 bit Java download for your operating system by clicking this link. Restart your launcher after updating.

Minecraft launcher

such as "-Xmx3G" (or "-Xmx3000M").

If you get stuck on any of these steps, or are having trouble finding the right amount to allocate or getting the game to run smoothly, check out the Fixing memory issues page or ask for help in the official Pixelmon Discord.
