Hello

I bought a laptop a few months back that is more than capable of running Minecraft in 64bit. I can supply more specs if required.

Whenever I boot Minecraft, javaw.exe takes up 400,000mb RAM (normal) and steadily climbs. In 15 minutes time, Java will have taken up all 8GB RAM, crashing my PC. Obviously this causes the frame rate to fluctuate. I have tried the following;

*Limiting the amount of RAM Java can take up upon execution of an application
*Installing 64 bit or 32 bit versions of Java on my 64bit machine
*Switching off and on features in the game
*Re installation of Java
*Uninstalling any conflicting apps (but nothing else uses Javaw.exe)
*Putting javaw.exe to high and realtime priority
*Changing the active cores from 2 to 1
*Using the web based applet in case the launcher was causing the problem
*Rolling back Java RE versions (tried current stable release and Java Runtime 5 stable)

None of this worked on vanilla Minecraft. Please help. There are other noted cases noted here (http://www.minecraftforum.net/topic/1335721-minecraft-125-memory-leak/).

Once again, please help. You can probably guess how desperate I am to play Minecraft again after my last computer broke.

Thanks in advance
Jack
