If you receive warnings that your virtual memory is low, you'll need to increase the
minimum size of your paging file. Windows sets the initial minimum size of the paging
file equal to the amount of random access memory (RAM) installed on your computer plus
300 megabytes (MB), and the maximum size equal to three times the amount of RAM installed
on your computer. If you see warnings at these recommended levels, then increase the
minimum and maximum sizes.
