simple calculation: (order of magnitude)
A0 ~ E-size is one square meter 

one A0 at 400 dpi is about 250 Mpixel, 
say 4 bytes per pixel (CYMK) is 1 GB uncompressed.
at 600 dpi it would become 2.3 GB
at 1200 dpi it would become 10 GB

If the area becomes larger it would scale up linear. 
So if the resolution/printarea becomes somewhat higher/larger
the 4GB limit comes within sight for uncompressed files.
