How to Give Minecraft More RAM on Java and Bedrock

Minecraft can use a surprising amount of memory, especially when mods, large worlds, shaders, or DLC are involved. Java Edition allows manual RAM allocation through the launcher, while Bedrock Edition handles memory differently.

How RAM Allocation Works in Minecraft

Minecraft Java Edition

Java Edition lets players adjust the maximum amount of RAM available to a specific installation from inside the Minecraft Launcher. Use these steps:

1. Open the Minecraft Launcher.
2. Select Minecraft: Java Edition.
3. Open the Installations tab.
4. Find the installation you want to edit. Latest Release is the default.
5. Hover over that installation, click the three dots, then choose Edit.
6. Select More Options.
7. Find JVM Arguments.
8. Change the number in `-Xmx4G` to the amount of RAM you want to allocate.

For example, `-Xmx4G` means Java can use up to four gigabytes of memory. Changing it to `-Xmx6G` raises that limit to six gigabytes.

Do not assign more RAM than your PC can comfortably spare. Giving Minecraft too much memory can create new problems, especially if the operating system and other programs are left fighting over the leftovers. Only change this value when needed or when directed by support, including HolyHosting support for relevant client-side troubleshooting.

Minecraft Bedrock Edition

Minecraft Bedrock Edition does not provide a manual RAM allocation setting for the client. Bedrock automatically uses the memory it needs, so there is no launcher field equivalent to Java's JVM arguments.

If Bedrock is lagging on your PC, check current resource usage instead. Press CTRL, ALT, and DEL together, open Task Manager, and review CPU and Memory usage.

If CPU or Memory is red or sitting near 100%, the issue may be limited available hardware resources rather than a Minecraft setting. Closing background programs, checking for system updates, or upgrading hardware may help depending on what Task Manager shows.
