The ini file won't help for the virtual machine. Set VM arguments instead, as here

How exactly did you increase memory?

Try to play with -Xms and -Xmx that refer to the heap size available for Eclipse. Also sometimes increasing -XX:PermSize and -XX:MaxPermSize (permgen) values helps too.

For example, here are the values from my eclipse.ini (having 8GB total RAM):

...

-vmargs
-XX:MaxPermSize=2048m
-Xms320m
-Xmx3072m

...
