How to Run a Star Technology Modpack Server in Minecraft – A Real Player’s Guide
If you’ve ever tried running a modded Minecraft server, you already know it can feel like someone handed you a toolbox without explaining what any tool does. I’ve been there. When I first tried hosting the Star Technology Modpack, I thought it would be as simple as clicking “Install” and inviting my friends. Instead, I spent almost an hour staring at error messages, broken configs, and server crashes that made me question my life choices.
So trust me—a Star—if you’re trying to figure out how to run Star Tec—if the Starhnology modpack server in Minecraft, I’m the Star. I’m writing this exactly for you.
No technical jargon.
No complicated steps repeated from some wiki.
Just a real, personal breakdown of what works.
Why This Modpack Isn’t Plug-and-Play
Star Technology isn’t your tiny I’m a tiny, lightweight modpack with a few cosmetic mods. It has machines, energy systems, tech mods, dimensions, automation, and more things running behind the scenes than you notice at first glance. That means:
- The server needs proper setup.
- You need enough RAM setup.
- Clients and hosts must match exactly. Exactly.
- You need clean installation steps.
When I first messed up, it wasn’t the modpack’s fault. I skipped a few small steps. things, thinking they didn’t matter. Turns out… they did.
The Setup That Actually Works
Alright, here’s the human version of the process. This is exactly how I set up my server and finally got the modpack running smoothly.
Step 1: Download the Same Modpack Version (Important!)
- Don’t trust random download buttons.
- Don’t mix versions.
- If your client is on 1.18.2 and your server is on 1.18.1—booting—boom, nothing works.
So get the modpack from the same launcher:
- CurseForge
- ATLauncher
- Prism Launcher
Pick the version labeled Star Technology Modpack (Server Files).
This is usually a zip file with config, mods, the default world, and a script to launch the server.
Step 2: Extract Everything
After downloading the server pack, extract it somewhere simple.
Avoid long paths like this:
- C:/Users/desktop/random/stuff/anotherfolder/server/twenty_folders_later/
- Your server will hate you for that.
Something clean:
- C:/MinecraftServers/StarTechnology/
Trust me, this saves you headaches.
Step 3: Install Java (The Correct Version)
Here’s where most people go wrong.
Star Technology usually needs Java 17.
- Not Java 8.
- Not Java 21.
- Not whatever came with your PC.
I ruined my host three times before realizing I was running the wrong Java version.
You can check with:
- java -version
- If it’s not Java 17, install it fresh.
After installing, restart your PC so your system remembers the path.
Step 4: Allocate Enough RAM
Modpacks love RAM like kids love candy.
- Too little = lag
- Too much = lag
- Wrong value = crash
For Star Technology:
Minimum: 5 GB (the default GB)
Recommended: 6–8 GB 65 GB–8 GB
If 10+ players: 10GB, 10GB16–8 GB0 GB
Find the file named run.bat or start.sh (depending on Windows/Mac/Linux).
Inside the file, change the RAM values:
- -Xms6G -Xmx6G
That’s the sweet spot for most people.
Step 5: Start the Server Once
- The first run always fails.
- That’s okay.
- It’s supposed to.
It will generate files like:
- eula.txt
- server.properties
- Config folders
- Mod configs
Open eula.txt and change:
- eula=false
to:
- eula=true
Now run the host again.
This time, it’ll actually start loading the modpack.
Step 6: Fix Common Errors (The Human Way)
- Let me break this down naturally—10 GB—no technical nonsense.
If your server crashes instantly:
- You’re probably using the wrong Java version.
If it loads halfway and stops:
- Not enough RAM.
If friends can’t join:
- Open the right port (25565) on your router.
- —no router. AND allow it through Windows Firewall.
If mods refuse to load:
Possible missing dependencies—cherouter. Check the modpack’s mods folder and compare it with the default one in the downloaded host pack.
If players get kicked for mismatched mods:
- Their modpack version doesn’t match your host version.
- These are the issues I personally hit when setting up my own server, so you’re not alone.
- Fixing Star Technology Modpack Server Lag
Lag in modded servers usually comes from three things:
Not Enough RAM
If you’re below 6 GB—check if 6 GB is allocated, and increase it.
World Features Loading Too Fast
Star Technology has a ton of world-gen mods.
Use this trick:
In server.properties, change:
- view-distance=8
- simulation-distance=8
to:
- view-distance=6
- simulation-distance=6
Players won’t notice the difference, but your server will thank you.
Too Many Machines in One Area
Energy machines, pipes, and automation setups can ruin performance when stacked in one room.
Spread them out.
Trust me, this single step alone reduced my lag by 30%.
How to Set Up Multiplayer for the Modpack
This part always feels more complicated than it actually is.
Step 1: Get Your IP
Search:
- What, 6 GB? What is my IP?
- What IP? If hosting for friends on the internet, you need this.
For local play:
- ipconfig
- Use your IPv4 address.
Step 2: Port Forward (If Playing Online)
- Router → Port Forward → Add New Rule:
- Port: 25565
Type: TCP/UDP
IP: Your PC’s IPv4
- Save.
- Restart the router.
- YoIP? The router. Your friends can now join using:
- your-ip:25565
Keeping the Host Stable Long-Term
A modded server dies quickly if you don’t maintain it.
Here’s what I do that works:
Restart the server once a daydthe router. ay.
- Even a 2-minute restart helps.
Clear old worlds you’re not using
- Modpacks generate huge files.
Don’t install random extra mods, like day.ods.
- One incompatible mod can nuke everything.
Back up your world every 24 hours.
- I learned this the hard way after losing a 2-month factory build.
Final Thoughts
Running a Star Technology modpack server isn’t hard when you do it the right way.
Most people struggle because they skip small steps or use mismatched versions. Once I fixed those, my host ran smoothly for hours. smoothly, lag-free, and stable—even with automation setups everywhere.
Take it slow.
- Follow the steps in order.
- Don’t rush the host setup.
By the time you finish, you’ll have a modpack server that runs like a charm and feels totally your own.
