Visual guide to allocating RAM

From Pixelmon Wiki
Revision as of 07:17, 1 May 2018 by Xpand (talk | contribs) (Updated for 6.2.3's lowered memory requirements. Also, added an SEO tag.)
Error: <seo> tag must contain at least one non-empty attribute.

By default, Minecraft starts up with only 1GB of memory to work with. While Pixelmon should work alright on the default allocation (as of 6.2.3), you may still wish to allocate more, especially when also running other mods. This quick guide will guide you through the process.

Minecraft launcher

Step Example
Start the Minecraft launcher.

Replace "-Xmx1G" with a higher amount,

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

Your allocation is now set, and should be ready to use! If your launcher is not letting you allocate more than 1GB, get a 64-bit Java download for your operating system from here, and then restart your launcher.

If you get stuck on any of these steps, or you are having trouble finding the right amount to allocate or getting the game to perform smoothly, feel free to ask for help in the official Pixelmon Discord.
