Hey guys!

So I am currently running Minecraft 1.7.10 on Magic Launcher with around 49 mods installed. When I login through Magic Launcher the game runs and everything is functional. When I go into the advanced settings for Magic Launcher, whenever I try to change memory input from 512MB to something higher the game crashes. This doesn't make sense to me because I have 11.9 usable RAM on my computer.

Does anybody know why Magic Launcher or Minecraft is doing this? Anybody know what the problem is exactly? Thanks in advanced guys!

Here is the crash report (view log) from Magic Launcher:

I'm not an expert at these, but looks like this is the important line:

"Initial heap size set to a larger value than the maximum heap size"

And below it, "Picked up _JAVA_OPTIONS: -Xmx512M"

I think Xmx512M is a parameter that limits ram to 512mb. Maybe you manually typed something like this somewhere while trying to optimize Minecraft? In that case deleting it should fix it!

Thank you sir!

But where can this be? Where is this code that I can just delete?

My first guess would be that it's in the Magic Launcher itself.

Options -> Advanced -> [Parameters]

Edit: It might also be somewhere in the Launch Options of the normal MC launcher that starts after Magic Launcher.

Alternatively, check this thread out: http://www.minecraftforum.net/forums/support/unmodified-minecraft-client/2183431-_java_options-picked-up-without-existing

Looks like the first reply there has a few solutions you might wanna try. Hope that solves your issue!
