i have faced the same problem earlier. but it is not the problem of max or vue now ur cameras,

just let me know ur pc config, which version of windows u using 32 or 64 bit?

when i faced this prob, it was because of 32 bit windows, even after having 6 gb ram n core i-7.
but when i switched to 64 bit windows, rendering worked correctly.

if u using 32 bit windows, then this problem will surely occur, bcoz ur machine wont use more then 2gb of Ram even if u hav more then that..

do have a look at ur stats, i.e... ur no. of polygons & faces... but i m very sure this prob, occurs due to win 32 bit...
