For Winblows 7:

1. Go to Control Panel
2. Search for Java, and click on it
3. Java Control Panel will open and you'll find 5 or more tabs, select the Java tab.
4.- Push the "View..." button for Configure Java Runtime Environment.
5 .- Here is the trick, java uses only 256 mb of memory for his own purposes, and Minecraft needs more than that.

See how much ram you have and increase java's memory usage as this:


Add this command in your Runtime Parameters on each entry that you have in this list. (Double click under Runtime Parameters) Add:

-Xmx1024m

EXACTLY as shown above no spaces with the minus symbol at the beginning and an "m" at the end.

in the above example, 1024 is the amount of memory that java will use, you can try 512 for small machines or 2048 for big ones.

javaw -Xmx4096m -Xms4096m -jar "C:\Users\Matt\Desktop\Minecraft.exe"
is the proper way to do this. 2gb for big ones lol...

make this into a batch file and change the users\matt to what ever you are...
this will force minecraft to run with 4 gb of ram

Well still, I have 6 gigs, and that would be 66% of my ram, JUST for java xD
