Minecraft
Allocate More Memory to Minecraft
Thought I'd share my success at memory allocation changes with those who are interested.
Note: I only changed my memory allocations on my machine due to in-game memory crashes every 90 to 120 seconds when exploring outside. Once I allocated 768m I haven't had a memory crash. This memory allocation started happening to my machine since 1.7.
I was trying various configurations to allocate memory but my command window would open up then immediately close or Java Virtual Machine (JVM) would not launch, etc.
I have Win7 Ultimate 64-bit, 12 GB RAM, with current version of Java installed.
I created a batch file & updated my PATH variable with directory of current Java version.
Batch file contains (use your own c:\path2minecraft.exe here):
javaw -Xms768m -jar "c:\minecraft\Minecraft.exe"
Added this to PATH (don't forget the semi-colon to separate this path from previous one):
;C:\Program Files (x86)\Java\jre6\bin
For Win7 Ultimate I right click Computer > Properties > Advanced System Settings > Advanced Tab > Environmental Variables > System Variables > highlight PATH then click EDIT. Add semi-colon then PATH to current version of Java then press Okay.
I've read about other people starting minecraft.exe with -Xmx parameter but I could not get various options to work, even though I have 12 GB RAM.
Side Note: The same machine runs minecraft flawless in Fedora Core 15 without memory modifications. Only the lack of Ventrilo support on Linux causes me to use Windows to run minecraft.
