Difference between revisions of "Visual guide to allocating RAM"

By default, Minecraft gives its clients 1GB of memory to work with. [[Pixelmon]] requires a bit more to work smoothly. If you're experiencing a lot of lag or the game is not starting, try this quick guide.

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 [https://java.com/en/download/manual.jsp clicking this link]. If you run Windows, make sure you get <code>Windows Offline 64 bit</code> specifically! Restart your launcher after updating.
