Help CenterSwitching modpacks on your SimpleGameHosting Minecraft Server takes just a few steps to get everything prepared. Let's go over the best way to change or switch your server's modpack.
🛑 IMPORTANT: Before switching modpacks, knowing how much RAM you will need is crucial.
How Much RAM Modpack Servers Need
The amount of RAM your server needs can vary based on several factors. However, since most modpack servers are not built to handle more than 5 to 10 players at a time, we use that range as a general guideline. Instead of focusing on the player count, it's more helpful to consider the number of mods in the modpack when estimating RAM requirements.
To make this easier, try our RAM Guide Calculator to find the best Minecraft server plan for your setup. If you want a more in-depth explanation, you can also check out our full guide on choosing the right RAMfor your server.
For modpacks available through our one-click installer, you can search for them here to see the minimum recommended RAM. If the modpack you are using is not listed, don't worry. You can still add it to your server manually.
General Guide
- Vanilla Server: 2 GB RAM
- Light Modpacks (fewer than 100 mods): 4-6 GB RAM
- Moderate Modpacks (100-200 mods): 6-8 GB RAM
- Heavy Modpacks (200+ mods): 8-10- GB RAM
⚡️ If you are experiencing lag or crashing on your server after installing a modpack, it is most likely a RAM issue. Upgrading your server may be needed. You can monitor RAM usage on your Panel.
Step 1: Log Into SimpleGameHosting Panel
To begin switching modpacks on your server, start by accessing theSimpleGameHosting Control Panel. Log in using the credentials you created when you purchased your server.
After logging in, you will be taken to the Console page.
Make sure your server is not running. To stop it, click the Stop button in the console. When the server status changes to Offline, it has been safely shut down.
Step 2: Clearing Your Server Files
Before installing a new modpack, it’s important to to stop the server and remove any existing files, game versions, or modpacks to avoid potential conflicts.
🛑Wait: We recommend creating a backup before proceeding. You can follow this guide to learn how. The following steps will delete your current world/setup.
1. Head to the console tab and press Stop to ensure the server is offline. Then go to the Modpacks and Versions tab to see if a modpack is currently installed.
- If a modpack is installed, click the Uninstall button in the top right corner, follow the on-screen prompts to confirm uninstalling the current modpack, and wait for the modpack to uninstall.
- If no modpack is installed, go to the Version Manager tab. If a game version is listed, click Uninstall next to it, and wait for the version to uninstall.
2. Open your File Manager, select all visible files, click Delete at the bottom, and follow the on-screen prompt.
3. Once everything has been cleared, return to the Modpacks and Versions tab.
Step 3: Install a New Modpack
Once your server is ready for a new modpack, you can use the Modpacks installer to begin the process. This page allows you to browse and search for modpacks from CurseForge, Modrinth, FTB, Technic, and VoidsWrath.
1. In the search bar, type Modpack name, press Search, and then click the Select Version button next to the modpack. Click the Install button and follow the on-screen prompts to begin the installation.
📒Note: When choosing a version, it is usually best to select the one at the bottom of the list, as this is typically the latest release. You can also check the release date shown on the page to confirm.
👋 Heads Up: Installation may take a few minutes depending on the size of the modpack. During this time, your server panel will be temporarily unavailable.
Step 4: Start Server
Once the server has finished the installation process, head back to the Console page in the menu bar. You can now hit the purple Start button in your console then wait for the server to turn online.
👋Note: Modpack servers can take several minutes to start for the first time. It isn't uncommon for a server to take 5 minutes to start with a large mods folder.
EULA Acceptance
If you deleted your 'eula.txt' file when removing the files from your server, you will need to accept it before your server will start. Normally, a popup will display on the screen asking you to accept the EULA.
If you don't see a popup, it's likely that your Console is frozen. In the text box, type 'true' and hit enter on your keyboard. This will accept the EULA and continue starting your server.
Step 5: Install Modpack Locally
In order to join your Minecraft server once the modpack is installed, you and anyone who plays on the server will need to download and install the modpack locally. Then, they will need to launch the modpack and join your server with a Minecraft installation that has the modpacks and all of its mods installed. Using the launcher for that modpack is the best way to get it. Here are links to the apps for the modpack launchers we support.
Unfortunately, every modpack is different, but there are amazing guides for playing Minecraft with specific modpacks that you can follow to get your modpack installed locally to join your server.

Step 7: Allocate Additional RAM (Optional)
Modpacks are incredibly resource intensive on both servers and your local machine. With a lot of modpacks, you may need to allocate more RAM to your game than the default amount.
Using the Vanilla Launcher:
1. In the Minecraft launcher, select Installations at the top. Then, find the installation you just added with the name of your new modpack. Hover over it and hit the three dots. From this point, hit Edit.
2. Scroll down to the bottom and hit More Options. Now, find the JVM Arguments text box.
3. At the beginning of the line of text, you will see -Xmx2G or -Xmx4000M. The numbers may change depending on how much RAM is already dedicated to the game. Change these numbers to increase the RAM. The amount you need will depend on the modpack you choose.
4. With the changes added, hit "Save."
Using the CurseForge launcher:
Minecraft Modpacks require a certain amount of RAM to run smoothly. If Minecraft keeps closing on its own when playing with a Modpack, you may need to assign more memory in the CurseForge launcher.
1. Launch the CurseForge app and click the ⚙gear icon at the bottom-left.
2. In the settings menu’s left sidebar, scroll down to Game Specific, then select Minecraft.
3. Scroll to Java Settings and locate the Allocated Memory slider.
💡Tip: Be sure to enable "Use modpack author’s recommended RAM settings when available" to help avoid memory allocation issues.
4. Move the orange slider to the amount you of RAM needed for the modpack. Then close the settings by clicking the back arrow button at the top left of the CurseForge app and your changes save automatically.
📝Note: Aim to set your allocation between 6000 MB and 10000 MB, but never exceed half of your computer or laptop's total RAM.
6. Start your modpack as usual on CurseForge. When you launch your modpack using CurseForge, you may see a warning about your RAM allocation being too low or too high. If it’s too low, just follow the steps above to increase it. If it flags too much RAM, you can safely ignore that alert and proceed.
7. 🎉You’re all set! You now know how to increase your RAM allocation in the CurseForge launcher.
💡Tip: You can verify your new RAM allocation in-game by pressing F3 and looking at the top-right corner.
Step 7: Play Your New Modpack
From the main menu click the Multiplayer button. Then you'll join your server just like you would with any other Minecraft server using your server's IP address. You can find your server's IP address on the Console page in your control panel.
Enter the server name (this will only appear in your game), enter the Server Address, and click the Done button. You will then be taken back to your server list, where you can select your server and click Join.
Modpack servers can take a few minutes to join sometimes, depending on the size of the pack.
