JAVA JAVA JAVA!
One of the most common problems people run into is minecraft giving the “Out Of Memory” error. This can be easily rectified. This will force windows to use more ram for Minecraft, and also have it use High system priority.
For windows (And I believe this works in both XP, Vista, 7, for 32bit and 64bit)
1) Open Notepad
2a) Type in the following for XP
start /high javaw -Xms1024m -Xmx1024m -jar "C:\Documents and Settings\Owner\Desktop\Minecraft.exe"
2b) Type the following for Vista or 7
start /high javaw -Xms1024m -Xmx1024m -jar "C:\users\Owner\Desktop\Minecraft.exe"
NOTE: Two things are variable here. One how much ram you want to allocate. 1024 = 1gb, which is enough for minecraft and some mods. If you use HD textures, you’ll want to allocate more. Do NOT allocate more ram than you have, and usually leave at least 500mb for the rest of the computer. The second is the location of minecraft.exe. This is assuming Minecraft.exe is on your desktop. Where Owner is bolded, that is your username on your computer.
4) Go to File > Save As
5) Name the file whatever you want. I suggest “Minecraft.bat”. The .bat part is the important part.
6) Click “Save as Type” and change it from .txt to “All Files” and save it in a convenient place.
7) Run the file. It should open a command window, and then open minecraft. The command window will close when you close minecraft.
NOTE: You can check if it worked by playing minecraft, opening a world, and pressing F3. If it worked, it should say “Allocated memory: 100% (989MB)” (assuming you allocated 1024. It will show more if you allocated more). If it DIDN’T work. The allocated memory should be 490ish still
MORE JAVA HELP!
Java 7 – Some people have reported that getting the beta version of Java 7 improves performance. Click the link. Click “JRE”, select x86 (for 32bit) or x64 (for 64bit) and install. Keep in mind that it is a beta, and while may improve performance, is not considered a stable build. I personally can’t use it, because it is incompatible still with several other java programs I use.
This is a list I’m slowly compiling on Java errors, and their fixes.
