Repost: How to increase the RAM usage for Minecraft

[Freddy705]

I, for some reason, really had some left over files from an old version. It didn't allow me to remove it though so I tried removing my current version which was Java 7 Update 1 and re-installing Java 6. It seemed like the old files and the new files merged, tried the batch file again and the error appeared again. I then decided to deinstall Java 6 too and install it again. Now it works.

problem solved? fuck yea

Hey, what if you get an error that says could not create java virtual machine? What should I do then? I followed the instructions at the top of the page as well as I could.

Do you have 64 Bit java?

As the title shows i have found a nice way to "fix" minecraft to run better on 64 bit systems. No its not taskmanager stuff but something else i fell over when searching the internet.

OK let me explain step by step


1. At [Desktop] (or anywhere you want) create a new folder. Name the folder for example "Minecraft"

2. Put ur minecraft.exe in the folder you just named "Minecraft".

3. Now right click in ur folder and Create new .txt file (name it what ever you want)

4. Open the .txt file and write this:

@ECHO OFF
"C:\Program files\Java\jre6\bin\javaw.exe" -Xmx2048M -Xms1024M -jar "The Path to where your minecraft.exe is. It this cause C:\Users\user\desktop\minecraft\minecraft.exe"


-Xmx2048M = maximum Ram minecraft can use
-Xms1024M = Allocated memory

If you want to be sure this works, press F3 ingame and look at the right side of the screen.

REMEMBER! Double-click the .bat file from now on to use minecraft with higher RAM. When you use the .bat file, minecraft will automatic open. If a black window apear and closes in 1 sec you have written something wrong in the path.
