Can I Allocate more RAM on Minecraft Server?

Yes, you can give Minecraft more RAM if you want to allocate. But there are certain requirements like your system needs to be 64bit, and it should have more than 3GB RAM. Without enough RAM, you will face spikes of lag in-game.

Right-click on This PC and Select Properties. Check for the System Type and If it’s x64 based PC then you can surely add an amount of RAM. But if it’s x84, that means 32 bit version of java is installed in your PC then, you won’t be able to allocate any more RAM to you Minecraft.

Now, come down in the list and look for Installed Physical Memory (RAM). This shows how much of available RAM you have in your PC.

Final Thoughts

Now, you can easily set the RAM of Minecraft like I have discussed in this tutorial. You can even set very high memory too(if you have enough).

But you will never need to run Minecraft with more than 8GB RAM although if you are playing with Mods.

If you have 8GB of RAM then you don’t need to add more than 75% of your RAM that means 6GB which will be good to go for you. There are some Modded Minecraft’s that require more than 8GB of RAM to run smoothly.
