Page file size on a Windows 7 64 bit system??? With 32gb RAM & (2) 240 GB SSD's in RAID 1 ??? RRS feed

  • Question

  • I have With 32gb RAM & (2) 240 GB SSD's in RAID 1 on a Windows 7 64 bit Ultimate system...

    I do run a tremendous amount of multi-tasking, however, I don't think I need that much virtual pagefile memory, if at all...

    I've reduced the initial size to 1024mb and 4096mb max for the pagefile... 

    I'm just wondering if it's necessary at all, and what effect completely disabling it would have on my system/performance?

  • Hi! Completely disabling it will cause many applications to run slowly or not run at all. Especially large softwares and games require a lot of virtual memory. So I think you should not decrease the values any further. Instead I suggest you to increase it more. Like 4096 MB initial and max 8192 MB.

  • So I took your advice and did 4096 to 8192... I did load test it prior to this though, and ran everything multi-tasked I could throw at it and it still had 10gigs of RAM unused, and had only used less than 1gig of paged memory for the paged kernel memory...

    Anyone else have any input here???????

  • Whats also weird is my "standby memory" (cached data) continues to constantly increase in the Resource Monitor tool...  Is there a way to control how much becomes cached?  now my 10gb free has decreased to 6gb...

  • You only need a pagefile of a couple hundred megs for a crash dumps, unless you're running out of memory, which seems unlikely.

  • Hi,

    Many of us believe that the page file usage shown in the task manager is the actual usage but this is not so. The below blogs will clarify it.

    I think that you should set the size of page file with long time observation, it is not the smaller the better.

    What is the Page File for anyway?

  • Mark Russinovich wrote about this (and talked about it in online videos as well).  Scroll to 'how big should I make the paging file'.  It's not the default.
