Do you simply want to know how much RAM you really use, and how big your Pagefile grows? This freeware executable does the job without any bells and whistles. MemStat's very basic text and bar graph interface clearly didn't have the input of a designer. However, it accurately and simply displays select system specifications along with RAM and Pagefile data.
MemStats doesn't graph totals over time. It displays Most Used and Least Used percentages for RAM and Pagefile. The upper and lower limits are only since the program was launched. The only way to reset the data is to close the application and restart it. Current totals are listed, but there is no way to freeze the information at a specific point in time. This is the tool you run in the background over a few hours to find out your RAM and Pagefile limits.
As an executable, MemStats can run off your USB tool kit or it can be quickly dropped onto a desktop and started. Anyone can run it and understand the results. If you worry that your system is maxing out RAM or Pagefile space, give this free tool a try.
