Well I decided to investigate further and fixed it myself.

Soooo... No solution?

I already have 3 GB, should I really add more? Edit: I tried putting 5 gb, still not working. I only have 8gb ram in total so can't really add more...

So basically I can run some modpacks but not the one I want to (Dungeon Realms). I have 64-bit Java and downgraded to the 1.8.0_25 one. I can launch some modpacks. The problem seem to be "java.lang.OutOfMemoryError: Java heap space" http://paste.ubuntu.com/18455153/
