virtual memory limitation for Windows 2000 Server

G

Guest

I'm trying to find out the maximum memory size that Windows 2000 Server will support for virtual memory. I know that the maximum RAM supported is 4 GB and that it is recommended that virtual memory be set to 1.5 times the amount of RAM. However, this is merely the recommended size. Does anyone know the maximum amount of virtual memory that Windows 2000 Server will support?

From what I know the only upper limits are a Max file size of 4 gig and
only as many page files as you have hard drive space available for.

Windows 2000 Professional and Windows 2000 Server support 4GB of Address
Space. Both physical and virtual memory are mapped into this address space.
The combination of physical AND virtual memory cannot exceed 4GB.

If you've got 1GB RAM then you may have a 3GB swapfile. If you have 2GB RAM
then your swapfile can only be 2GB.

Actually, that is not quite accurate: The way that Windows manages it
memory is quite a bit more complicated than that.
Much more than 4GB of virtual memory can be used, because the Memory
Manager is able to "fool" each User Mode process into thinking that there
is only 4GB.
In reality, you can have multiple programs open, each being able to use 2GB
of User Mode memory, and each being able to see the 2GB of Kernel Mode
memory that is reserved for the OS and drivers. The memory manager handles
shuffling all this memory around, be it in the Physical Memory or Paging
File.
