This certainly isn't universally true. That is, I haven't seen this on any of the 64-bit Mac or Windows machines I routinely use with Stata 11 64-bit.  They have 8 G or 4 G modules/cards and I frequently allocate and use (without virtual mem) 30 G or more (on machines with 32 G or 64 G physical RAM). Maybe there are other systems that have this limit(?)
