Visual guide to allocating RAM
On some setups, Minecraft may start up with only 1 GB of memory to work with. While Pixelmon may run with this low allocation, allocating more often helps performance and stability. This is especially true when also running other mods. This quick guide will guide you through the process.
Stuck on 1 GB? A 64 bit install of Java is required to be able to allocate more than 1 GB of memory. You can get a 64 bit Java download for your operating system by clicking this link. If you run Windows, make sure you get
Windows Offline 64 bit specifically! Restart your launcher after updating.
