I've checked all the other answers and I can't seem to find one that fits my situation. I'll go ahead and list everything I've tried, that way we can cruise through the generic answers.

Heads Up: New PC. Downloaded Java 64x. Copy and Pasted old PC's .minecraft folder. Same specs except for CPU and GPU. It is Modded.

Problem: Everytime I launch Minecraft without allocating any RAM it starts fine but with only 500MB of RAM allocated. I can't add arguments or I get a "Java Virtual Machine" Error. Changing the Environment Variables doesn't affect the 500MB of allocated RAM. If I just add the -Xmx1G etc... argument it launches with 500MB of RAM regardless, unless I add more than 4GB then it spits out the "Java Virtual Machine" error.

Things I've Tried

  • Installed Java 64x
  • Reinstalled Java 64x
  • Re-reinstalled Java 64x
  • Ensured I was using 64x Java and not 32x
  • Made changes to Environment Variables
  • Turned it off and back on again
  • Set specific arguments
  • Reinstalled Minecraft.
  • Re-reinstalled Minecraft.
  • Forced Minecraft to Update (with an error)
  • Googled fixes for several hours
  • Found nothing
  • Posted here and several other places.
  • Awaiting replies...

*Also, don't know if this is important, but the Java website can't verify my Java.

  • Could you give some specifics about the Java version you're trying to use, as well as the Minecraft version, your Windows version and the command you're trying to use to start Minecraft? – Nzall Feb 27 at 15:55

    Also be good to know how much available RAM you have... – Stese Feb 27 at 16:06
  • also, how much minecraft starts with isn't important, it requests RAM up to the limit its been allocated. If you want it to start with more, use Xms<ram>. – Stese Feb 27 at 16:15

    Do you mean "64 bit"? Because I doubt you really installed Java 64 times. Also, what's the error you get? – Fabian Röling Feb 27 at 18:27

    I honestly don't know what was causing it but it managed to fix itself after the third attempt at restarting and relaunching minecraft. – Mr. Wulf Feb 27 at 21:17
