Quote - If your Poser is still 32bit then, unfortunately, it still has the 4GB limit.
This is a misconception...
32 bit is limited to a total of 4 gig of total addressable space.
232 = 4,294,967,296 bytes 4,294,967,296 / (1,024 x 1,024) = 4,096 MB = 4GB
There is no way that you can use 4gig with a 32 bit program, it isn't possible.
If your video card has 512 meg of ram, (low for example) you loose ram before the bios even finishes. You end up with about 3 gig left. Add a video card with even more memory, and it gets worse. Once Windows (or any other op system) comes up, the kernel, services, and any programs that auto launch consume even more. Some of this can not be cached, and must remain in main memory. All of this takes away from the total free ram. Two 1 gig video cards will drop you to 2.2 gig left for programs.
To further complicate matters a 32 bit operating system can only access one page of memory at a time, and the maximum page size in Windows is 2 gig per page. If you have a machine with 32 bit Windows, a decent video card, etc. You will be left with 2 memory pages. A 2 gig one, and whatever is left after that. Possible only one page depending on the hardware. Large Aware just lets a program (that knows how) access a second page, that may or may not even be there to begin with.
Using 4 gig in 32 bit Windows is a myth..
