    Hello everyone,

    On a 32-bits architecture, the maximum size for a process is 2GB on windows.

    Do you know what is the maximum size on the 64-bits architecture on windows?

    Is it something I can find on the microsoft site?

    Not find it yet.

    Regards,

    I suppose it should be bigger, but I am not sure how the available memory space is split.  For example, on a typical 32bit machine, you have 4GB of addressable memory - OS stuff is mapped into 2GB of it, and each app gets the lower 2GB.  The /3GB switch that you can add to boot.ini alters this split to 1GB/3GB.  As for 64 bit, you'd need to find the split - I would be interested in hearing if anyone knows this info too!!

    7152 GB on IA-64 (Itanium) and 8192 GB on x64 systems (Source: Microsoft Windows Internals, 4th Ed p.375).

    Strange amount of GB on Itanium system..  Spose 3GB could also be seen as a strange amount on a 4GB system too

    Thanks for that - maybe it will appear in Trivial Pursuit one day
