do you use coupled solver? because coupled consumes more memory (around double the segregated solver)

have u activated both of the processor (you have dual)? because I read in a fluent newsletter, that you must activate both processor first.

there is unwitten rule that 1 GHz is for 1 million grids (for segregated), around 500.000 for coupled. but this number is just approximation
