I have a HP Dv6 with 6 gb ram, core i7 win 7, 1 card onboard Intel and an ATI HD 6770M. When I worked with a 20mb project, my revit 2012 64bit use 4gb ram. I think it's so much for a small project 20mb When I check on my friend's laptop, also revit 2012 64bit but it used just 1gb ram. Because my revit use 4gb and even 4.9gb of ram so it lagged and then crashed. Does anybody meet this problem? Please help me
