Minecraft may be a challenging application due to its simple aesthetic design and extremely basic gameplay. Once you actually play with redstone-heavy build games, there's a ton of processes going on in the background. If you put modifications into the equation, then suddenly the normal quantity of RAM Minecraft uses is simply not enough.
Other difficulties that practically unplay the game will start to hit you without sufficient RAM. This approach will undoubtedly aid you in increasing the memory space of RAM that Minecraft can use to fix memory issues. You may simply assign RAMs from launcher versions 1.6 to 2.0.X if you are using the personal Minecraft versions; at the lower-left angle of the launcher window, you can verify your version of the launcher number.
You need to generate a file to run Minecraft with extra memory when you update a RAM server. It is a good idea not to allow Minecraft to get more than half to two-thirds of the total RAM of your machine.
Make Sure that You Can Spare RAM
The first step is to find out how much RAM you have on your PC. This is simple.
- Select the Settings icon from the Start menu (it looks like a gear).
- To learn more, go to About.
- In the menu under Device Specifications, look out for Installed RAM in your system. The number beside it indicates the size of RAM available in your system.
At least 2 GB of RAM is essential for Minecraft, however, 4 GB is advised. You're in good shape if you have more than that. You may now give Minecraft as much RAM as it needs to satisfy its requirements.
Method 1: Use the Default Launcher to Allocate RAM
Although originally it was not possible, the default Minecraft launcher has evolved over time and now you may increase the amount of RAM available to Minecraft.
- Choose the edition you wish to play within the Minecraft Launcher (either Bedrock or Java)
- Choose Installations from the top-level tabs. There is a list of releases beneath, but if you have not specified any specific editions to play, you may just see the newest latest release.
- Drag your pointer over it, then select the three white lines on the right-hand side, then select Edit.
- A screen will be displayed with the title of the installation, the edition, and a few other choices. Scroll down to More Options and look for JVM Arguments. There will be a lot of code in this box, but you only need to care about the first snippet, which looks like this:
- The figure at the end represents the amount of RAM used by Minecraft. Change the "2" to the amount of memory or RAM you wish Minecraft to utilize.
It is feasible to let it utilize all of the RAM you have accessible, but whether it truly takes advantage of full usage depends on whether you have something else operating and running in the background.
- After you've finished making your modifications, click Save and launch the game. You should notice an instant change in performance.
Method 2: Allocate RAM in Windows 10
Here's how to increase the amount of RAM your server can utilize. Please remember that these instructions are only for servers operating from a Windows 10 PC.
- Navigate to the folder that contains all of your Minecraft server directories.
- Select "New" and "Text Document" from the menu that appears when you right-click on any black space in the folder. And temporary, you may call the file whatever you like.
- Open the document and insert the following code:
java -Xmx####M -Xms####M -exe Minecraft_Server.exe -o true
Instead of "####," enter the quantity of RAM you wish to assign. You'll input the allocation in megabytes, thus if you wish to allocate 3GB, type "3072," creating the code:
java -Xmx2048M -Xms3072M -exe Minecraft_Server.exe -o true
- When entering the quantity of RAM you want, be sure your GB to MB conversions is right. Now, choose "File," then "Save As..." Change the "Save as type" to "All Files" in the option that appears. Keep it.
Saving as "All Files" allows you to alter the document's extension afterward.
- Once you have successfully saved the document and it is visible in your folder, rename the file as "file server launcher.bat" - without quotation marks.
- What started as a text file has evolved into the new Minecraft server launcher. Double-click the new.bat file to restart your server with the increased RAM.
Method 3: Use the ATLauncher to allocate RAM.
You're probably acquainted with the ATLauncher for Minecraft if you've downloaded mods or played a lot of heavy build games like Sky Factory. Setting aside additional RAM with the ATLauncher is even simpler than with the usual launcher, especially because no code-writing is required.
- Start the ATLauncher application.
- On the right-hand side of the launcher, there is a list of options. Go to the top of the screen and select Settings, then the Minecraft/JAVA tab.
- There are other options to select from, but the second one – Maximum Memory/RAM - is the one you want. You can put in the amount you wish to assign, but clicking the up and down arrows is the simplest choice. This changes the amount of RAM allotted in 0.5 GB increments.
- Once you've decided how much RAM you want to use, click Save. If you're playing a module-heavy pack like SkyFactory, you'll need more RAM; otherwise, the game won't start. Sky Factory 4 required at least 4 GB of RAM in our tests, else it would crash on launch.
Method 4: Use the Twitch/Curse Launcher to allocate RAM.
You may also use the Twitch launcher to play a number of Minecraft modifications (or regular Minecraft). Changing the settings in this launcher is just as simple as it is in the ATLauncher above, but the first technique for doing so is a little different.
- Click the three lines in the top-right corner, then Files, then Settings. CTRL + Comma will direct you to the Settings menu from inside the launcher.
- Then, in Minecraft, scroll all the way down to the bottom. A pane titled Java Settings will be shown. Find and select the Allocated Memory slider.
- Sky Factory 4 is given 3,228 MB of RAM by default. To assign more or less RAM for the game, drag the slider to the left or right. The RAM is increased or decreased in 0.25 GB increments using the slider.
- You're done after you've moved the slider. Return to Mods, pick Minecraft, and begin playing your better-performing title. It's as simple as that.
Hence we saw four different methods on how to allocate more RAM to Minecraft for a smoother experience. But you have to remember allocating more and more RAM can sometimes overall slow down your system. So you should be careful when you trade your RAM to enhance Minecraft performance.
