Minecraft Forums

Whenever I try to launch minecraft with more than 1gb of Ram I get sent to a tab called Game Output, but it does not say anything in the game output.

I have the JVM arguments checked and I have -Xmx4G in the text box but it still will not work. I have 64 bit java installed, and I have a 64 bit computer with 8 gigs of RAM.

My Launcher Log Is this:
