Question Windows 10 New Build Lots of RAM Issues

[aoresteen]

I just finished the Win10 part of a build I have had on hold for 18 months. The mobo is an ASUS Prime Z790M-PLUS D4, CPU is i9-13900KF, 128GB RAM, and I have lots of storage. I am using an 250GB SSD to boot Win10 and Linux Mint 21.3 from, each getting 110GBs. The Windows partition was almost used up during the install as Windows 10 created a 53GB hiberfil.sys file and a 19GB pagefile.sys. I was shocked as the C:\Windows folder was only 20GBs in size. I turned off hibernation and got the 53 GBs back.

Why would Windows even create a pagefile.sys with 128GB of RAM in the system? I put 128GB of RAM in so that I wouldn't run out of RAM. If I really need a pagefile.sys I have plenty of other places to put it but I really don't want such a large file in my boot partition. Can it be moved safely? Thoughts?

Thanks!

That made me curious as on a few computers I also have 128 Gb of memory as well. Never thought about the page file size.

Mine seem to all be at 19456 MB default.

Don't really know why yours took so much for pagefile?

My guess is windows needs a space large enough to handle what is in ram if you use hibernate.
You have the ability to decide what size to use for a page file.
