you own 64Gig RAM and a pagefile of again 64gig is waste of disc space and can have more a negativ effect… I have this, because I own 64gig too, on 1024MB 
… we have a huge topic about these pagefile. Important is this for users with less than 32 GIG RAM or users with 32 GIG RAM and usage of very demanding mods.
Also be aware that there are topics in case you use externalized views, which is seemingly the case.
