Minecraft Not Using All of RAM
My Minecraft has been crashing a lot lately. I've tried everything, batch files, going into the Control Panel settings, all I could. This is the problem:
When I play Minecraft, I turn on my F3 view. The RAM will go up and up in percentage until it reaches 20% of RAM being used. It will then go back down to 8%. But if it gets to 21% or RAM being used, the game will crash.
How do I fix this problem?
Edit: I was going through my Downloads folder and found three Java error messages, most likely from Minecraft. Here is the message:
Second Edit: Somebody asked me to determine if I had the path set up correctly by informing me to do the following:
An easy way to determine this is fire up your CMD and type java -d64 -version. If it returns a successful message, you should be running the 64-bit version of Java.
The result was the command box displayed that it was an unrecognized function and could not run the JVM. I'm guessing it is because the path is not set up properly. How do I set the path to the 64 bit version of Java so I can use it with Minecraft?

Are you running the 32-bit version of Java? If so, download and install the 64-bit version. 32-bit Java has a fairly low limit set on the amount of memory it can allocate.
This will only work if you're running a 64-bit operating system though.
If that's not the issue, try to post the crash log if you can. If you're using mods and have ModLoader installed, take a look at the modloader.txt file in your .minecraft folder right after a crash. Specifically, the lines near the end of the file. It could shed some light on your problem.
I have successfully solved my RAM problem! The trick is to put to do the following:
Download Java 64-Bit (if you have a 64-bit computer)
Put a Minecraft shortcut onto your desktop
Right click the shortcut and choose properties
Tell Minecraft to use 64 bit Java with the following code (put this code in the target):
"C:\Program Files\Java\jre6\bin\java.exe" -Xmx1024M -Xms512M -cp Minecraft.exe net.minecraft.LauncherFrame
Not only does this tell Java to use more RAM, but also shows it the location of the 64 bit Java.
I hope others learn from my mistakes! Thanks for the help everyone!
