Minecraft and memory issues

January 21, 2023

“Minecraft”, especially when you have mods or texture packs that enhance the graphics, can be quite impressive.

The more “Minecraft”, the more RAM it will need to run. If the game doesn't have enough RAM, it will load slowly, frame will stutter and even crash.

There is a way. There are many ways to increase RAM for “Minecraft”, each one quite simple and straightforward.

You can also add more RAM to your server if you have it running as “Minecraft”, which allows you to allow more users to play at once.

Here is a list of all the methods to increase RAM for 'Minecraft.

Important: This guide is only applicable to “Minecraft Java Edition”. There is no way to limit the amount of RAM used by “Bedrock Edition”, also known as “Minecraft For Windows 10”.

Quick tip: Always have at least 2 gigabytes of RAM (GB) for “Minecraft”. Consider increasing your RAM to 4GB or 6GB if you plan on using many mods.

Be careful to not take in more RAM than you actually have. It is important to have at least half of the RAM left for other purposes.

Allocating RAM using the default launcher 'Minecraft.

You may be familiar with Minecraft's default launcher app called “Minecraft Launcher”. This is how you can use it to reallocate RAM.

3. To access two more fields, select “More Options” at the lower-right corner.

4. The “JVM Arguments” field begins with a bit code that says “-Xmx2G”, or something similar. This is the number of gigabytes of RAM Minecraft can currently use (in this instance, 2GB). You can change the amount of RAM that is allocated by changing this number. The rest of the text should remain unchanged.

5. To save your changes, tap “Save”.
