So I'm trying to run minecraft with more ram, and I have 8 GB of RAM, and when I try, it says "Error occurred during initialization of VM. Could not reserve enough space for object heap. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit." Anyone have any ideas? Do I have to Allow Java to run minecraft with more memory? Here's the code I'm using. Just throwing it in a batch file.

java -Xmx2G -jar "Minecraft.exe"

Tried using GB instead of MB, and MB instead of GB. Tried using Capital and Lowercase MB and G, tried running as admin, tried running in CMD, none of them work. Could it for some reason have to do with me being in windows 8 by any chance?

Just tried using magic launcher, and that doesn't even work O.o

Are you using 64bit Java?

Yup. At least I'm assuming. My Java is in Program Files (x86)

x86 is 32bit Java. Install 64bit Java here,
