No, 600MB isn't the maximum RAM capacity. It's just a specific amount you're checking.
They should have noted the limited RAM availability, which is just 1.5GB.
It would be really shocking if vanilla FO3 played at 1.5GB LMFAO, considering how long the game has been around.
It looks like your 580 handled well, but using the ENB caused some geometry issues. Haha!
