The Essentials of RAM in a Minecraft Server

Before diving into the specifics of how much RAM you need, let’s quickly cover what RAM is and why it’s so important for Minecraft servers.

RAM (Random Access Memory) is the temporary memory your server uses to run processes and store data it needs to access quickly. For Minecraft, this includes things like loading world data, handling player actions, managing mods and plugins, and more. The more RAM your server has, the more it can handle at once.

When running a Minecraft server, having enough RAM ensures that the game world runs smoothly without lag or crashes. But, how much is enough?

Vanilla Minecraft Servers Versus. Modded Servers

Vanilla Minecraft Servers

For a vanilla Minecraft server (one without any modifications), the amount of RAM required is relatively low, especially for smaller groups. If you’re just running a server for a few friends to enjoy a casual game of Minecraft, a few gigabytes of RAM will likely suffice.

• 1-4 players: For a small vanilla server with up to 4 players, 2GB of RAM should be more than enough. This allows the game to run without much lag while managing the basic world data and player actions.
• 5-10 players: As your server grows in size, you’ll need to bump up the RAM. For around 5 to 10 players, 3-4GB of RAM is recommended. This will ensure the server can handle the increased world data and player interactions smoothly.
• 10-20 players: For a server with 10 to 20 players, you should consider allocating around 6GB of RAM. This ensures that the server can handle multiple players while keeping the world loaded without too much lag.

Modded Minecraft Servers

If you plan on running a modded Minecraft server (with mods, plugins, or custom features), things change a bit. Mods add extra complexity to the game, requiring more resources to load and manage additional content. A modded server can easily demand more RAM than a vanilla server.

• Small modded server (1-5 players): For a small modded server, you may need around 4GB of RAM at a minimum. This gives the server enough power to handle the additional load caused by mods while still keeping things relatively smooth.
• Medium modded server (5-10 players): For a medium-sized modded server, 6-8GB of RAM will be necessary to manage the extra world data, modded content, and player interactions.
• Large modded server (10+ players): If you’re planning to run a large modded server with 10 or more players, you’ll want 10GB or more of RAM to ensure the server can handle the increased load without lag or crashes.

Factors That Affect RAM Requirements

Several factors influence how much RAM your Minecraft server will need. Here are the most important ones:

1. Server Type (Vanilla vs. Modded)

As mentioned earlier, modded servers will require more RAM compared to vanilla servers. This is because mods add complexity by introducing additional data, items, mobs, and interactions that need to be processed.

2. Number of Players

The more players you have, the more resources your server will need. When players join a Minecraft server, the server must load and manage the world data around them. More players mean more data to handle, which increases the demand for RAM.

3. Server World Size

The size of your Minecraft world also plays a role. Larger worlds require more RAM because the server has to store more chunks of the world, which increases the amount of data the server must process. If you have a huge custom world with lots of structures and terrain generation, you’ll need more RAM to keep everything running smoothly.

4. World Features (Plugins, Mods, etc.)

Running plugins or mods can significantly increase the amount of RAM your server needs. Mods like Pixelmon or large plugins that alter the game’s mechanics will use more memory to function properly. Additionally, some mods may introduce features that require more frequent data processing, further increasing RAM usage.

5. Server Software

The type of server software you use can also affect your RAM requirements. For example, PaperMC or Spigot (which are optimized versions of the default Minecraft server software) generally perform better than the vanilla Minecraft server and may reduce the amount of RAM needed to run a server smoothly.

6. Additional Settings

Sometimes, specific settings you apply to your Minecraft server can impact how much RAM it uses. For example, if you’re running a highly detailed world with lots of custom features, you might need to allocate more RAM to avoid lag. Similarly, enabling features like world border or adjusting view distance can affect your server’s RAM usage.

How many RAM Do You Require Based on Your Server Size?

Let’s take a deeper look at how much RAM is recommended depending on the number of players and server features.

1-10 Players

For a small Minecraft server with up to 10 players, 2GB to 6GB of RAM should be sufficient, depending on whether you’re running a vanilla or modded server. A vanilla server would only need around 2-4GB, but a modded server might require 4-6GB.

10-20 Players

For servers with 10 to 20 players, you’ll want to increase your RAM to 6GB to 10GB. If the server is modded, lean toward the higher end of that range.

20+ Players

When hosting a server with more than 20 players, it’s a good idea to go for 10GB to 16GB of RAM. Larger player counts require more RAM to ensure that everyone’s game runs smoothly, and performance doesn’t dip, especially if you’re running mods or plugins.

Suggestions for Optimizing RAM on a Minecraft Server

While the amount of RAM is important, it’s also crucial to optimize how that RAM is used. Here are some tips to help you get the most out of your server’s memory:

1. Use Server Optimization Plugins

There are several plugins designed to help optimize server performance, reducing the strain on your RAM. ClearLag and NoLagg are two popular choices that help manage entities and prevent memory leaks.

2. Adjust Your View Distance

The view distance setting controls how much of the world around each player is loaded at any given time. A higher view distance increases RAM usage. Reducing the view distance from the default 10 chunks to 8 or 6 can save memory and reduce lag without sacrificing too much visual quality.

3. Reduce the Number of Active Plugins/Mods

Only install the plugins and mods that are necessary for your server. Excessive plugins or mods that aren’t optimized for performance can eat up a significant amount of RAM. Regularly review and remove unused or outdated ones.

4. Upgrade Your Hosting Plan

If you’re running a Minecraft server on a shared hosting plan, you may need to upgrade to a dedicated or VPS server. These plans offer more control over your server’s resources and will allow you to allocate more RAM as needed.

5. Monitor Server Performance

Regularly monitor your server’s performance with tools like Spark or Timings to identify any areas where RAM is being overused. These tools can help pinpoint plugins, entities, or world features that are consuming too much memory.

Conclusion

the amount of RAM required for a Minecraft server depends on various factors such as server type, number of players, world size, and whether you’re running mods or plugins. For a small vanilla server with up to 10 players, 2-4GB of RAM should suffice, while modded servers with more players may need 6GB or more. Larger servers or heavily modded worlds may require 10GB or even up to 32GB for smooth performance. Optimizing server settings, managing plugins, and regularly monitoring performance can help ensure the server runs efficiently. Ultimately, understanding your server’s unique needs will guide you in selecting the right amount of RAM. Regular updates and maintenance are also key to avoiding performance issues. By balancing RAM allocation and server optimizations, you can provide an enjoyable Minecraft experience for all players.
