yes my mistake...
32bit application can access to max 4gig

and heres more i found on google:
"4GB is the maximum amount of memory 32bit (unsigned)
pointers can address, the space addressable within one segment is often
limited to 2GB, the maximum of a signed 32bit pointer"

whatever that means (im not a programmer..i dont understand that)


and heres what i find in maya help..

"Memory exceptions maybe encountered even though Maya reports that free memory is available

On some 32-bit machines (including Irix, Windows, and Linux) virtual memory is restricted to 1.6 Gbs (or thereabouts). It doesn't matter if you have hundreds of giga-bytes of physical memory or swap, no process can grow larger than this size. Maya may encounter a memory exception and report that there is still lots of memory available."


anyone here experienced any benefit in maya after using memory above 2gig?
