A. RamMap is a great tool from the Sysinternals site that gives detailed information of how memory is being used on a Windows OS. The tool can be downloaded from Microsoft and presents memory information in many different ways including:

  • Use Counts: usage summary by type and paging list
  • Processes: process working set sizes
  • Priority Summary: prioritized standby list sizes
  • Physical Pages: per-page use for all physical memory
  • Physical Ranges: physical memory addresses
  • File Summary: file data in RAM by file
  • File Details: individual physical pages by file

The main tab of the application gives summary information, as shown here.
