I am assuming you play on Windows since you siad i7-7700k. The type of computer is not what matters, it is the RAM. Don't you have a bat file that makes you run the server? Don't always just click on jar file to start the server. If you don't have a bat file, make one. To do this go to your text editor and make a new file. Inside that new file, write "java -Xmx [Most RAM Wanted] -Xms [Least RAM Wanted] -jar [Name for the jar of your minecraft server] .jar nogui". Fill in the brackets and paste it into your text editor. (Make sure to delete quotations!) The most RAM wanted is the maximum RAM you want to allocate to your server. The Least RAM Wanted is the least amount of RAM you want to allocate to your server. In my opinion, I suggest you to use 4GB for the most RAM wanted and 1GB for the least RAM wanted. The command for this would be: java -Xmx4G -Xms1G -jar [Name for the jar of your minecraft server] .jar nogui

 

If it keeps crashing, keep adding more RAM but don't add more then 8GB. Hope this helps!

The more RAM you add the longer Garbage Collection could potentially take to run AFAIK

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/: 100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

i did it right? i made a start.bat file and wrote there "java -Xmx4G -Xms1G -jar forge-1.12.2-14.23.4.2744-universal .jar nogui"

I forgot to mention that the text file can't be just named "Start.bat". You must go into the text editor, press save as, and there, you enter .bat as the file name. Windows may give you a warning, but just press ok.  Once you made the bat file, the icon should look like two gears.

 

To run your server, just click on it. It will open a command prompt, showing the server console.

 

 

Keep in mind a modded server is the same as a vanilla server basically, but with mods. Search up a tutorial about making a server. The person should show you how to make the bat file.

Where did you hear this, @PulseBeat_02?

 

I think your issue there is Windows is set to hide known file extensions by default, so the file is actually Start.bat.txt but you only see the start.bat portion, in your file explorer window go to the view tab and check the file name extensions box.

 

Once this has been done you can run the bat file in CMD by typing its name or by simply double clicking on it, also I highly recommend adding pause to a new line the end of your Start.bat, this will make sure the window doesn't auto-close after your server closes, making sure you don't miss any console output.

I have the same problem and i tried this and got errors

Invalid maximum heap size: -Xmx4G
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

 

Do you know what i should do about this.
