In another thread I just posted in this was said:

No 32 bit version of any OS will support over 4GB of RAM. In fact, do to page memory allocation, you will only see about 2.8-3.2GB on a Win XP 32 bit or Vista 32bit machine.

Actually, that's not technically true. Any *single process* will only see 4GB of RAM, because the virtual address space will be 32 bits due to register size. But on an Intel CPU anyway, a 32 bit OS can make use of much more RAM than that, and spread it out among the individual processes. It's basically the same segmented architcture that has been there since the 186/286 years, but the segments are now 32 bit. The full theoretical memory capacity of a 32 bit Intel CPU is quite huge for that reason, and it doesn't have any of the complexities (for the programs I mean) that the original (16 bit) memory segments caused since each process will just see a single, flat 32 bit address space. It's only the OS that has to deal with that extra layer of virtual address mapping.

It's just that Windows, I assume for reasons of compabitility with other CPUs that don't provide that capability, doesn't choose to make use of this feature. It's kind of a bummer since in the end Windows' multi-platform capabilties came to naught and it really only is ever deployed on CPUs that do provide this segmented architecture, AFAIK. Of course it would also make the OS memory management more comlex, but the CPU provides a lot of support for that stuff.

So anyway, it wouldn't give SONAR any more *virtual* memory space, because of the issue of mapping things into each process' high GB of virtual address space. But it could mean that SONAR could have a full 4GB of physical memory to itself because the overall memory capacity could be 64MB or whatever and each process that required it could have that full 4GB, with none taken by other processes. That wouldn't make a huge difference for some folks, but for others it could very much help if they are running other large apps at the same time.


So this could mean I can rewire Tascam Gigastudio into Cakewalk Sonar 7. So a system with 10 GB memory and 8 cores on WINXPPRO should show 3.2 free memory. But when the two apps are started and setup both should get their own space of 4GB and thus the system benefits of cores and memory on a dual quad. Offcourse the system should have three disks. One OS one SAMPLES and one audio.

JCCHILD have you tested this and is there added benefit?
