Easy and more than one way to do it
Despite its low graphics style and relatively simplistic gameplay, Minecraft can be an application intensive. There’s a lot going on in the background, especially if you start playing around with heavy red stone constructions.
If you throw mods into the mix, the standard amount of RAM Minecraft needs to run suddenly becomes less than enough. Without enough RAM, you will start to experience stutters, crashes, and other issues that make the game almost unplayable.
Make sure you have spare RAM
The first step is to determine the exact amount of RAM your PC has. It’s easy.
- Click on Start and select the icon Settings (it looks like a gear).
- Click on “To about “.
- In category ” Device Specifications “, look for ” Installed RAM “. The number next to it will tell you how much RAM you have.
Minecraft requires a minimum of 2GB of RAM, although the recommended specs call for 4GB. If you’ve got more than that, you’re gold. Now you can allocate all the RAM Minecraft needs to quench its thirst.
Method one: allocate RAM from the default launcher
The original, default Minecraft launcher has changed over the years, but you can always allocate more RAM for what Minecraft is using.
- Open the Minecraft Launcher and select the version you want to play (either Bedrock or Java)
- Select Facilities in the tabs at the top. You’ll see a list of versions below, but if you haven’t set up specific versions to play, you might only see the most recent version.
- Hover your cursor over it and click on the three white dots on the right side, then click Edit.
- You will see a screen with the name of the installation, the version and a few other parameters. Click on More options and scroll down until you see the arguments of the JVM. This box will contain a lot of code, but all you need to worry about is the first snippet that looks like this:
- The number at the end is the amount of RAM Minecraft is using. Change the “2” to the amount of RAM you want Minecraft to use.
It is possible to let it use all the RAM you have available, but to know if it is actually taking advantage of full use, you need to know if you have other things running and open in the background. .
- Once you have made the change, click Save and start the game. You should see a difference in performance immediately.
Method two: allocate RAM from the AT launcher
If you’ve downloaded mods or played a lot of SkyFactory, then you are probably familiar with the ATLauncher launcher for Minecraft. The ATLauncher makes it even easier to set aside more RAM than with the default launcher, especially since it means you don’t have to work with any code to make it happen.
- Launch the AT launcher.
- On the right side of the launcher is a list of options. Select Settings, then the tab Java / Minecraft at the top of the screen.
- You have several options to choose from, but what interests you is the second, that of the maximum memory (Maximum Memory / RAM). You can enter the amount you want to allocate, but the easiest way is to click on the up and down arrows. This allows the amount of allocated RAM to be moved up or down in 0.5 GB increments.
- Once you have selected the amount of RAM you want to use, click Record. If you are playing a mod heavy pack like SkyFactory, you will need to allocate more RAM or the title will not launch. During testing, Sky Factory 4 required at least 4 GB of RAM or encountered errors during startup.
Third method: Allocate RAM using the caster
You can also play a variety of Minecraft (or normal Minecraft) mods through the Twitch launcher. Changing the settings is as easy in this launcher as it is in the AT launcher above, but the initial method of reaching those settings is a bit different.
- In the upper right corner click on the three lines, go to Files, then click on Settings. You can also press CTRL + comma from the launcher to open the Settings menu.
- From there, navigate to Minecraft and scroll down to the bottom. You will see a section titled Java settings. Look for the allocated memory and click on the cursor.
- By default, it gives Sky Factory 4 3,228MB of RAM. You can move the slider left or right to allocate more or less RAM for the game. The slider increases or decreases RAM in 0 increments, 25 GB.
- Once you’ve moved the slider, you’re done. Navigate again to the Mods, select Minecraft, and jump into your best performing title. It’s as simple as that.
Allocating more RAM to Minecraft can (and in many cases will) make Minecraft perform better, but there are situations where allocating too much RAM goes decrease the overall system performance.
Other areas of your PC also require RAM. While these areas are not very important if they are not running at the same time as a game, it is often a good idea to budget at least 1 GB of RAM for other non-game processes.
If you change your RAM settings and you still don’t see the performance you expect – or if your PC is reporting an incorrect amount of RAM – this may indicate other issues with your memory. It’s a good idea to check your memory every now and then.
The good news is that even if you have a problem with your RAM, swapping it out is easy. In fact, if you are looking for even better performance, it is worth considering purchasing more RAM for your system, especially as the price of memory continues to drop.
