About this video: This video is our complete guide on how to add more RAM to Minecraft 1.20.4. We cover truly everything from how much RAM Minecraft 1.20.4 needs with and without mods to how to give Minecraft 1.20.4 more RAM inside the Minecraft Launcher, we cover it all!

First things first, how much RAM do you need in Minecraft 1.20.4? Well, it really depends on what you are doing in Minecraft. For vanilla Minecraft without any mods, you don’t really need more than 2GB to 4GB of RAM. However, once you start modding Minecraft 1.20.4, this change and more RAM is needed.

For example, if you use 50 or fewer mods, 4GB of RAM is still good enough. However, change that to 50 to 100 mods, and you’re looking at around 6GB of RAM. The story changes even more with 100+ mods as we recommend going to 8GB or even 10GB-12GB of RAM depending on how many mods you have. Modpacks with 300+ mods can use 12GB of RAM depending on the mods that are in them.

It’s also worth noting that you should never add more than half of your computer’s total RAM to Minecraft. For example, if you have a computer with 16GB of RAM, we suggest not adding more than 8GB of RAM to Minecraft in order to leave some RAM for the rest of your computer.

If you want to know how to see the amount of RAM you have on your computer in order to not give Minecraft 1.20.4 too much RAM, just search for “System Information” in the Start Menu. Here, you will see an “Install Physical Memory” option. This is the amount of RAM (memory) your computer has.

Now that you know how much RAM you should give Minecraft, let’s go over how to allocate more RAM to Minecraft 1.20.4. Start off by opening up the Minecraft Launcher. Then, go to the “Installations” tab to the top. Here, you will see all of your Minecraft installations. This will work for modded Minecraft as well.

Hover over the Minecraft 1.20.4 installation you want to add more RAM to and click the three dots that appear. Click on “Edit”, and the click the “More Options” drop-down text. You will now see a “JVM Arguments” text box.

At the beginning of this text box, there is a “-Xmx2G”. It could be a different number in the text. That is because the number listed here is the amount of RAM you have dedicated. Changing this number to 4 (-Xmx4G) will give Minecraft 4GB of RAM. To add more RAM to Minecraft 1.20.4, just change this number. For example, “-Xmx8G” add 8GB of RAM.

After you have added the RAM, click “Save” and play Minecraft using that installation. To see the amount of RAM Minecraft 1.20.4 has dedicated to it, press the “F3” key on your keyboard. You will now see the RAM Minecraft has dedicated to it in the top right of Minecraft in MB. So 4GB is 4096MB of RAM.

With that being said, you now know how to allocate more RAM to Minecraft 1.20.4. If you have any questions about how to add more RAM to Minecraft 1.20.4, let us know in the comments. We will try our best to help you out.

Can you do a tutorial on how to turn an old PC into a Java+bedrock home server? I’ve looked at other channels but they don’t explain the process nearly as well as you do.
