How to add more ram to a mine craft server

Do you want to know how to add more ram to a Minecraft server? It's simple! Minecraft servers require lots of memory, so adding more will ensure that it doesn't crash or lag too often. In this blog post, I'm going to show you how easy it can be by doing a step-by-step tutorial

What is Minecraft?

Minecraft is a game where you build blocks in an infinite world. Also, some monsters want to kill you. You can explore randomly worlds and build amazing things from simplest homes to grandest castles. You can also play in creative mode with unlimited resources or mine deep into the world in survival mode, crafting weapons and armour to avoid dangerous mobs. Create, explore and survive alone or with friends on mobile devices or Windows 10.

What is a Minecraft server?

A Minecraft server is like another computer where users go and play on. People usually create their own private servers so only certain people can log in while others cannot. This makes it good for playing with friends. You can even create your game modes (like anarchy, prison, survival games..)

Minecraft server requirements:

Here are the Minecraft server requirements:

- 4GB of RAM (64-bit Java), recommend 8GB or more

- 2 cores minimum, 3+ recommended (Intel E5 class CPU recommended)

- At least 1GB of available disk space (SSD recommended) - 64-bit Java installed

There are no specific server requirements for plugins or mods, but be mindful that too many can cause lagging. To find the threshold at which the server starts to lag or crash, adequate testing should be done.

Explaining RAM Usage in Minecraft Servers:

Minecraft servers will need lots of rams for the server to function. This is because java uses much memory, especially when many players are connected at once. There are two kinds of memory usage in java: heap and stack. The heap is where normal objects are stored, while the stack is for temporary variables. Here's an explanation from stackoverflow.com:

How to add more RAM to Minecraft server?

In this step-by-step tutorial, I will go through how to add more RAM to a Minecraft server. It's pretty simple and will only take 5 minutes.

First, open SSH on your server (if you don't know how, just follow this guide and skip the part about putty). Then connect with your.username@yourdomain.com using the password you set previously (in my case, it is Minecraft ).

Then type this command: echo 'export JAV_OPTS="-Xmx2G"' >> ~/.bashrc This will tell java to allocate more memory. The double-gig after 2 is equal to 2048. This limit is 2048, which is equivalent to 4GB ram.

Then, exit the SSH connection by pressing CTRL+D Then restart SSH by typing in this command: service ssh restart. Now you can check your memory usage with this command free -m And it should say like this: total free shared buffers cached Mem: 3009 2647 352 0 72 2653 -/+ buffers/cache: 256 2763 Swap: 1542 986 556

Below are other proven methods you can allocate more ram:

Allocating RAM using the default launcher:

To allocate more ram for your server when you launch it from the default launcher, do the following:

1. Click on "Edit Profile."

2. Click on "Use version."

3. Check the box that says "JVM Arguments."

4. Type in -Xmx2048M (equivalent to 4GB RAM)

5. Click "Save Profile."

Allocating More RAM using the AT Launcher launcher (Proven Method):

This method has been tested and works, and it will allow you to allocate more ram:

1. Open the launcher

2. Click on "Launch Options."

3. Check the box that says "JVM Arguments."

4. Type in -Xmx2048M (equivalent to 4GB RAM)

5. Click "Save Profile

Allocating more RAM on the FTB Launcher:

If you want even more ram than the ATLauncher offers, here's a tutorial on how to set up memory allocation for your FTB Modpack.

1. Click "Edit Profile."

2. Click on Properties next to Java Arguments. You will see something like this, make sure you have the following selected: -Xmx2048M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+AggressiveOpts

3. Then click on the gear button and select 2048 (equivalent to 4GB)

4. Save Profile and Run Pack (don't forget to make sure you have FTB selected beforehand)

If you want to allocate more ram, use a higher number. Keep in mind that the max amount of ram available is 4GB for 32-bit java and 8192MB for 64-bit.

Twitch App or Overwolf:

You may notice that Minecraft starts to lag or even crash when running Twitch or Overwolf. To fix this, follow these steps:

1. Click on the settings cogwheel (over wolf) or gear (Twitch)

2. Click on "Advanced":

3. Uncheck the box next to "Compress screen updates."

4. Click Apply

Void Launcher:

If you have many mods installed on your server and you find that it is lagging or crashing, follow these steps:

  1. Open VoidLauncher.
  2. Click "Mods".
  3. Tick the box next to all the mods installed on your server. In my case, it is IndustrialCraft BuildCraft and Forestry.
  4. Go back to the main menu, click "Mods" again and then click on "Launch Options" under Industrial Craft.
  5. Type in -Xmx2048M (equivalent to 4GB of ram).
  6. Open Minecraft and join your server like normal.

It is a proven method and works very well. You can even allocate more than 2048. You will need to do this for each mod that has issues on your server regarding lagging or crashing.

Conclusion :

You can use several proven methods to allocate more ram for your Minecraft server, but it will depend on the amount of mods you have installed. These modifications should allow you to run a stable and smooth Minecraft server. This tutorial is meant for just getting the most out of your hardware.
