Ouch. 600 is well outside the design range. You might have to play with neutering parts of the non-linear solver. For example, basically turning off the newton steps because computing the Hessian means something like 2*600*600 recalculations of your target cell.
Also, the polishing steps are probably a waste of time for you. See also http://www.solver.com/hard-models -- that is written about a different solver but the basic points apply here too.
