Improve the Performance of Minecraft: A Simple Windows RAM Upgrade

How to Increase RAM in Minecraft: Resolve Lag and Boost Performance

Alright, fellow Minecrafters, if your game is lagging, stuttering, or crashing, it’s probably starving for more RAM—especially if you’re rocking heavy mods and HD texture packs. "The good news?" Increasing Minecraft's RAM allocation is a simple way to achieve buttery-smooth performance. Let us dissect it!

Step 1: Check How Much RAM You Have

Let us check what your computer is capable of before adding more RAM to Minecraft:

Right-click the Windows Start Menu and select Settings.

Head over to System > About.

Look under Device Specifications and note your installed RAM.

Got at least 8GB? Cool. If you're running 4GB, don’t even think about boosting RAM—your system needs it more than Minecraft does.

Step 2: Allocate More RAM in Minecraft Launcher

If you’re using the default Minecraft Launcher, follow these steps:

1. Open Minecraft Launcher and click on the Installations tab.
2. Find your preferred game version, hover over it, and click the three dots (…) on the right.
3. Select Edit > Click More Options (bottom right).
4. In the JVM Arguments field, find this line:

-Xmx2G 

That "2G" means Minecraft is using 2GB of RAM. Change the number to whatever amount you want (e.g., "-Xmx4G" for 4GB). Just don’t go crazy—leave at least 2GB for your system.

5. Click Save, launch the game, and enjoy the speed boost!
