Star Technology modpack transforms Minecraft into a sci-fi adventure packed with tech mods, space exploration, and automation systems. Running your own server means you and your friends can build massive factories, explore dimensions, and automate everything without the lag and limitations of single-player or random public servers.
What Is Star Technology Modpack
Star Technology is a tech-focused modpack that combines popular mods like Mekanism, Applied Energistics 2, Thermal Expansion, and Galacticraft. It’s built around progression through different technological eras, starting with basic machinery and advancing to nuclear reactors, quantum storage systems, and interplanetary bases. The modpack typically includes 100-200 mods depending on the version, with heavy emphasis on automation, power generation, and resource processing.
Quick Answer: To run a Star Technology modpack server, you need a dedicated server with at least 6-8GB RAM, Java 8 or newer installed, the Star Technology server files downloaded from CurseForge or the modpack launcher, and proper port forwarding configured on your network. The server requires more resources than vanilla Minecraft due to complex mod interactions and chunk loading.
Server Requirements for Star Technology
Don’t skimp on hardware with this modpack. Star Technology isn’t vanilla Minecraft, and trying to run it on a potato will give everyone a slideshow experience.
Minimum Hardware Specs
- RAM: 6GB minimum, 8-10GB recommended for 5+ players
- CPU: Modern quad-core processor with good single-thread performance
- Storage: 10GB SSD space (HDDs will cause chunk loading delays)
- Upload Speed: At least 10 Mbps for smooth multiplayer
The RAM requirement jumps significantly as players spread out and load more chunks. Each player building automated systems with chunk loaders will increase memory usage. Budget an extra 1-2GB per active player beyond the first three.
Hosting Options
You’ve got three main routes: self-hosting on your own hardware, renting a VPS, or using managed game server hosting. Self-hosting works if you have a spare PC and solid internet, but you’ll handle all the technical stuff yourself. VPS gives you flexibility but requires Linux knowledge and manual setup.
Managed hosting eliminates the headache. GameTeam.io offers Minecraft server hosting with mod support starting at $1/GB, and they’re running a limited-time 20% off promotion. One-click modpack installation beats spending hours troubleshooting Java versions and port forwarding.
Installing Star Technology Server Files
The installation process differs slightly depending on whether you’re using CurseForge, ATLauncher, or Technic, but the core steps remain similar.
Download the Server Pack
Head to CurseForge and find the Star Technology modpack page. Look for the “Additional Files” or “Server Pack” section. Some modpack creators provide a separate server download, while others require you to export it from the launcher.
If there’s no dedicated server pack, launch the modpack in your client, go to the profile settings, and look for “Export” or “Create Server” options. This generates the necessary server files without all the client-side mods.
Server Setup Process
- Extract the downloaded server files to a dedicated folder
- Locate the forge installer file (usually named something like “forge-installer.jar”)
- Run the installer and select “Install Server”
- Wait for the installation to complete and libraries to download
- Edit the “eula.txt” file and change “eula=false” to “eula=true”
- Create a startup script with proper memory allocation
Memory Allocation Script
Create a batch file (Windows) or shell script (Linux) with these parameters:
Windows (start.bat):
java -Xms6G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -jar forge.jar nogui
Linux (start.sh):
#!/bin/bash
java -Xms6G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -jar forge.jar nogui
The -Xms flag sets minimum RAM, -Xmx sets maximum. The G1GC garbage collector handles modded Minecraft better than the default. Adjust the memory values based on your available RAM.
Configuration and Optimization
Fresh server files need tweaking before they’re ready for players. Default configs rarely work well for multiplayer environments.
Essential Server Properties
Open “server.properties” and adjust these settings:
- max-players: Set realistic limits based on your RAM
- view-distance: Reduce to 6-8 for better performance
- simulation-distance: Keep at 4-6 to reduce server load
- spawn-protection: Adjust or disable based on your needs
- enable-command-block: Set to true if using automation
Mod-Specific Configurations
Navigate to the “config” folder and look for performance-heavy mods. Applied Energistics 2, Mekanism, and chunk loading mods need attention.
For chunk loaders, limit how many chunks each player can keep loaded. Open the relevant config file (FTBChunks, ChickenChunks, or whatever the modpack uses) and set reasonable limits. Five loaded chunks per player is generous; more than that can tank performance.
Mekanism configs let you adjust power generation rates and machine speeds. If players are rushing through content too fast, tweak these values. The config also controls gas and fluid tank sizes.
Applied Energistics 2 has settings for channel requirements and power consumption. Channels add complexity but prevent lag-inducing mega-networks. Consider leaving them enabled unless your group prefers simplified gameplay.
Performance Mods
Add these server-side performance mods if they’re not already included:
- AI Improvements: Optimizes entity AI pathfinding
- Clumps: Combines XP orbs to reduce entity count
- FPS Reducer: Server-side version reduces background processing
- Spark: Profiling tool to identify lag sources
Network Configuration and Port Forwarding
Your server won’t be accessible without proper network setup. Minecraft servers use port 25565 by default, but you can change this in server.properties if needed.
Port Forwarding Steps
- Find your router’s IP address (usually 192.168.1.1 or 192.168.0.1)
- Log into your router’s admin panel
- Locate the port forwarding section (sometimes called “Virtual Servers” or “NAT”)
- Create a new rule forwarding port 25565 to your server’s local IP
- Set protocol to TCP or Both
- Save and restart your router if required
Use a static IP for your server machine or set up DHCP reservation to prevent the local IP from changing. Nothing’s more annoying than port forwarding breaking because your router assigned a new IP.
Common Problems and Solutions
Server Crashes on Startup
Usually caused by insufficient memory allocation or mod conflicts. Check the crash log in the “crash-reports” folder. Look for “Out of Memory” errors or specific mod names mentioned repeatedly. Increase RAM allocation or remove problematic mods.
Extreme Lag with Multiple Players
Use the Spark profiler to identify bottlenecks. Common culprits include excessive chunk loaders, too many active machines, or entity-heavy farms. Implement chunk loader limits and ask players to optimize their builds. Quarries and mob farms should use void upgrades or item deletion systems.
Players Can’t Connect
Verify port forwarding is configured correctly. Test using an online port checker tool. Make sure Windows Firewall or antivirus isn’t blocking Java. Players need the exact same modpack version installed on their clients—version mismatches cause connection failures.
World Corruption
Set up automatic backups immediately. Use a plugin like FTB Backups or create scheduled tasks that copy your world folder. Tech modpacks with complex tile entities are more prone to corruption if the server crashes during a save.
Best Practices for Server Management
Establish rules about chunk loaders and automation early. Unlimited chunk loading kills servers fast. Set boundaries for how many machines can run simultaneously in one area.
Schedule regular restarts every 12-24 hours. Modded servers develop memory leaks over time. Automatic restarts with warning messages keep things running smooth.
Monitor your server resources using tools like Task Manager, htop, or your hosting panel. Watch for memory creep and CPU spikes. Address issues before they become unplayable.
Create a Discord or communication channel for your server. Players need somewhere to report issues and coordinate. It’s easier than troubleshooting blind when something breaks.
Frequently Asked Questions
Can I add extra mods to Star Technology?
Yes, but test additions in single-player first. Ensure new mods are compatible with existing ones and don’t require different Forge versions. Always backup before adding mods to a live server.
How much does it cost to host a Star Technology server?
Self-hosting is free aside from electricity. Budget hosting starts around $10-15 monthly for adequate specs. Premium managed hosting with better hardware and support runs $20-40 monthly depending on player count and RAM allocation.
Do players need to install anything special?
Players need the exact same modpack version installed through their launcher (CurseForge, ATLauncher, etc.). They can’t connect with vanilla Minecraft or different mod versions. Share the modpack name and version number clearly.
How do I update the server to a new modpack version?
Backup everything first. Download the new server files, copy your world folder and configs to the new installation, and test thoroughly. Some updates change mod IDs or remove mods entirely, which can cause item loss or world corruption.
Why is my server using so much RAM?
Tech modpacks with automation, chunk loaders, and complex tile entities consume significant memory. Each loaded chunk with active machines adds to RAM usage. Review chunk loader usage and optimize player builds. Consider upgrading RAM if you’re hitting limits consistently.
