hi,

try it with these additional create options:
-co BIGTIFF=YES -co TILED=YES

BIGTIFF allows you to exceed the 4GB
TILED should speed up the reading of the output file as reading of small 
parts of the image

Have a look at http://www.gdal.org/frmt_gtiff.html for other create 
options for the tiff format and http://www.gdal.org/formats_list.html 
gives you a hint of the maximum file size

Wolfgang
