Here Is How Much RAM You Should Allocate to Minecraft

Boost RAM Feature
Share:

If you’ve ever played Minecraft Java Edition, you’ll be familiar with the game lagging on occasion. Sometimes, if you’re playing multiplayer, it can be related to internet connection problems, but it can certainly happen even in single-player games. You’ve probably heard about RAM affecting gaming performance and giving FPS boosts to end the lag problem, and you’ve likely also heard that you can allocate more RAM to Minecraft. So the question is, how much RAM should you allocate to Minecraft?

  • Article Breakdown:
  • The recommended amount of RAM you should allocate to Minecraft is 4 GB, but this only applies to ideal conditions.
  • If you’re playing on a server or have a computer with low memory, you should allocate even more to it.
  • This, however, does not have anything to do with actual gameplay.
  • These are the recommended specs of your computer. For vanilla Minecraft, it’s best to allocate 2 GB.

What does RAM do?

The purpose of RAM is to store short-term data that your PC requires to operate correctly. The more RAM you have, the more actions you can take without the computer lagging. Everything you do on your computers takes RAM, even browsing the internet.

The gaming community, for example, has an issue with one of the most used browsers out there: Google Chrome. The simple explanation is that Google Chrome sucks up a lot of your RAM apart from the fact that it never stops collecting user data to adjust how they display ads and which ads they show you.

There are browsers with far better RAM allocation than Google Chrome. I personally use Opera GX because it allows me to set a RAM limit so it won’t spend any more RAM than I assign it, but I digress.

Minimal and recommended system requirements for Minecraft

It used to be that you didn’t need a beast of a PC to run Minecraft. While that still holds true to some extent, in practice, it’s far from it. Today, you have the minimum and the recommended system requirements for running Minecraft. The minimum ones will allow you to run it, but it’s almost guaranteed that you’ll experience low FPS and a ton of lag, so I’ll only mention the recommended system requirements.

CPU – Intel Core i5-4690 3.5GHz / AMD A10-7800 APU 3.5 GHz or equivalent
RAM – 8GB
GPU – GeForce 700 Series or AMD Radeon Rx 200 Series
HDD – 4GB, but SSD is better
OS – 64-bit recommended, Windows 10, macOS, Linux from 2014 and above

When you look at these requirements, it turns out that you need an excellent mid-range PC to run Minecraft properly. Mid-range PCs aren’t expensive, but they don’t come cheap either. The 8 GB of RAM does not mean Minecraft will use up all that RAM just to run; PCs use RAM to function, let alone play games.

Should You Give Minecraft More RAM?

Both too much and too little RAM are terrible news regarding how much you allocate to the game. It might seem like too much can’t be wrong, but it’ll affect performance in the same way that too little does, so you should allocate RAM according to your needs and what applies to you.

I’m not saying Minecraft doesn’t run better with more RAM, but allocating too much will affect your PC performance. As mentioned previously, PCs need RAM to boot up and run, so taking that RAM away is a terrible business.

So how much RAM should I give Minecraft?

The simplest way to figure out how much RAM you need to allocate to Minecraft is to follow the rules in this table. Take what applies to you, and change the RAM allocation accordingly.

Playing With Lightweight Mods4-6 GB
Playing With Complex Modpacks6-8 GB
Playing With Most Complex Modpacks And Other Visual Mods8-10 GB

It’s clear now that Minecraft doesn’t take a lot to run, but thanks to our ability to mod it (only if you’re a Java Edition player), it takes more and more to run correctly. Since part of the fun with Minecraft is that you can mod it, you have no choice but to either buy better components or not use that many mods.

These are just references, and many users report that the RAM allocation sweet spot is 4 GB. Any more than six and you’ll run into problems. However, that is not always the case, so it’s best to allocate it depending on your situation. You can look at the debug screen to know where you stand.

Using the debug screen to learn how much you should allocate

meM

To open up the debug screen, press F3. Then look at the upper right corner, and you’ll see a row that says Mem:. Mem stands for memory, and it’ll look something like this with the number varying: Mem: 31% 1878/3008MB. Let’s dissect what each of the components means.

The number before the slash is how much RAM Minecraft is currently using to run, and the number after the slash tells you how much RAM you’ve allocated. Take some time to look at the percentage. The peak percentage should be between 60 and 80%. Any higher than that, and I’ll affect your performance.

So to translate, the lower the percentage is, the better it is. If it’s too high at its peak, you need to allocate more, and if it’s low all the time, perhaps you’re giving too much and can lower it.

How to allocate more RAM to Minecraft?

Allocating more RAM to Minecraft can be done in many ways, but the easiest one is to go into your Minecraft launcher and change the values, so follow these steps to do just that:

  1. Open up your Minecraft launcher and navigate to the Installation tab
  2. Once you’ve opened it, click on the three dots located to the right of the Latest Release
  3. Select Edit
  4. A new window will open and take you to the setting of Minecraft. Once you’re there, click on More Options
  5. Scroll down and find the JVM arguments. Within the text, you should locate the text that mentions a number followed by the letter G. It should be at the beginning of the text.
  6. Change the number value to whatever you see fit but don’t overdo it.
  7. Click Save and restart Minecraft.

Where to learn about PC specifications?

If you’re running a Windows 10 or 11 PC, you should click on your Start Button, go to Settings, and click on System. From there, you should scroll down and click on About, which should show you your PC specs. The process is a bit different if you’re a Mac user but it yields the same results.

In your Apple Menu, go to System Settings and navigate to General in the sidebar. Click on About, located on the right, and finally, press System Report. A shortcut would be to press and hold the option key and then choose Apple Menu and System Information.

How does RAM affect games in general?

We’ve already discussed how allocating too much RAM to Minecraft can affect performance but didn’t discuss why that is. If you allocate too much RAM to Minecraft, specifically when the game only uses about 4GB max, the remaining GB is left unused. In games, enough RAM usually means you’ll get slightly better FPS, the game will run more smoothly, and the loading times will be reduced.

There’s a lot more that affects how the game plays on your PC; RAM is just a minor part. As games get more demanding regarding how strong of a computer you need to run them, RAM requirements increase, but it’s not the only thing that increases. A good PC is balanced throughout all of its components. Have something to add? Let us know in the comments below!
