@nanan00 I would bet that if you have 64 Gb RAM and you set your paging to let Windows manage it that your Windows automatically defined recommended paging file is larger than 32 Gb RAM.

 

I have 32 Gb RAM and yet my automatically defined recommended paging file size by Windows is 49 Gb...

The rationale for setting the Pagefile size manually with Min and Max set identically was to keep the file from becoming fragmented on the disk if it was dynamically grown.  File fragmentation theoretically could then slow the read/write performance when paging becomes necessary.

 

Not sure this is still an issue with defrag built into Windows and capable of defragmenting the Pagefile, most everyone running SSD's where access times are insignificant, and typically more physical memory than is actually needed to run the active application which means a Pagefile may never actually be used unless a system dump due to a crash is performed.
