Basically a 32bit system has available 4gb of virtual address space of which 2gb is for a application and 2gb for the OS. This space allocated has nothing to do with physical ram or page file and each application uses its own space . Now if the USERVA setting and the patch everyone is talking about is applied to a application then the amount of virtual address space can be amended ( in the boot.ini file or equivalent depending on OS ) so that the application has more than 2gb but it also means that the OS has less than 2GB of this 4gb virtual address space which can cause other problems such as system instability if too much is taken away. A typical setting for the USERVA might be USERVA=2560 or less.markpullinger wrote:Have heard several mentions of this userva patch but no idea what it is or what it does! Perhaps the techie talk could be explained please - & not by being refered to a hardware forum
Now I might have got some of that wrong so those who know more feel free to correct it.
