Hey guys, I am not sure if this is a Forge problem or? 

 

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 view log:

Minecraft 1.7.10 is no longer supported here. You should update.

 

The -Xmx is probably being set in an environment variable, which can be set/altered in control panel if you have windows.
