Question Virtual Memory And Physical Memory
If I choose to rais the amount of virtual memory the system uses does this meen that the computer will not show as much Physical Memory or not be able to utalize it?

Virtual memory is actually not memory. It is simulated memory area on the HDD. When you are using a lot of virtual memory, your system will actually run slower. HDD access is considerably slower than RAM access. The OS will page memory out to the HDD to make more physical memory available to itself or applications, as needed.

If you raise the virtual memory/pagefile size, it will not affect the amount of physical memory available. You probably are concerned because of the 4 GB memory address limit, but that only goes for physical memory. Virtual memory does not count into that.
