That was for the default model , 2 other models are available :
32-bit Large Memory Model
The large memory model is selected by specifing -bmaxdata:0xN0000000, where N
may be 1-8. This allocates N memory segments for user data and also allows the
user stack to completely occupy a segment. The maximum number of segments that
can be used for user data is 8.

32-bit Very Large Memory Model
The very large memory model is selected by specifing -bmaxdata:0xN0000000/DSA,
where N may be 1-8. This allocates upto 8 memory segments for user data, but
the segments are allocated dynamically. In AIX 5.2 the maximum number of
segments increases to 10 with the stack having its own segment, or 13 if the
stack segment is shared with shared library text and data. Under AIX 5.1
(current version running on p690) the limit is the same as for large memory
model, 8.

64-bit Memory Model
64-bit memory model can address up to 1 Exabyte of memory. 256 MB memory
segments are still used, but ~4,300,000,000 segments are available instead of
16. Segments are dynamically allocated within specified ranges for various
uses. User data can occupy up to 448 Petabytes of memory. The 64-bit memory
model is selected by specifing -q64.
