Do I install it over top of the existing gantry framework, or do I remove the existing gantry component first?
Switch to a Joomla template.
Uninstall Gantry
Refresh caches
Install Gantry
If you still have error then check Admin -> Site or System -> System Information -> PHP Information -> Core -> memory_limit. It should be a minimum of 64MB or preferably higher.
If thats OK then the best way to debug this is to grab a free copy of
Akeeba backup
and clone your site to a subfolder. Then on the debug site start UNINSTALLING your NON-Joomla/Rockettheme plugins one by one till you find the culprit.
I will say I've never seen Akeeba backup, Akeeba admin tools and RS Forms Pro have such an effect with Gantry.
