can't increase -Xmx beyond 1300m despite 16gb RAM

Hey,

I've looked up various threads about increasing memory for Gephi, but I'm not able to understand why I can't put in any number higher than 1300 for -Xmx in gephi.config. The computer I am working on has 16gb RAM installed. If I put in a higher number in the config file, Gephi does not open (I click on the shortcut and nothing happens). However, the problem is that when I have -Xmx1300m, the file I'm trying to analyze won't open as Gephi will show me a message box telling me RAM assigned is insufficient.

I have no clue what I should do at this point. Any suggestions?

You probably have a 32 bit java installed. Make sure to install a 64 bit Java 8 (x64) http://www.oracle.com/technetwork/java/ ... 33155.html
