Solved Question about virtual memory and nvme.2

OK, I have 2 NVME.2 machines, one for Windows and the other for games.
On the Windows hard drive, I configured the page file as desired.
I'm curious, Can I also include the second NVME2 and raise the page file?


Thank you

You certainly could. Technically speaking, it would work fine.

But you already have set an 80GB page file, when windows would recommend 5GB. Seems like increasing it would just eat up drive space providing no tangible benefit.

How much RAM do you have? And why did you set a custom size rather than letting Windows just manage it?

What are you trying to accomplish? And how much memory do you have?

I have 32gig of memory, and just let Windows Manage the Page File. Been doing that since I left XP, where I used to set the Page File myself. Now I just let Windows do it. Never had any performance of memory issues doing it that way.

everything is in my sig

I choose to use it because it's effective and I have ample space available.

In theory moving the pagefile (or the larger portion of it) to a seperate drive from the OS could improve performance as the pagefile would not be impacted by i/o calls to the OS drive.
This used to be more of a thing with spinner drives which have much higher latencies and reduced concurrent i/o operations available, but with modern SSDs, of all types, the performance improvement would be negligible to non existant for the majority of users, especially if the pagefile is not being hit regularly due to lack of available physical RAM.
There are few reasons to not allow Windows to manage pagefile placement & size, although some niche setups may benefit from custom settings.

If someone wants to set larger than needed pagefiles and have as many as they have drives then let them do them.
I would be interested in the OP's reply of "It's effective", in what quantifiable manner is it effective? Just curious.

It's really not effective anymore and especially with more than 4gig of RAM and thus why I leave it to Windows. That's me.

Anyway, it's your PC, and if you feel more comfortable doing it that way, do it.

Peace.

From Shakespeare -- "A little Learning is a Dangerous thing".

Yes you've got enough RAM and disk space but unless you actually understand how the OS internals work and have a concept of how demand paging, task management, task scheduling, I/O subsystems etc. all work (all OS'es work on with those prime elements) then you are wasting your breath, resources and anything else that matters.

Windows itself is by far the best management of those resources --user tampering usually in around 98% of cases fails to improve performance and usually makes it worse.

I doubt if it really is "effective" as you say and what tools are you using to measure it with.

Anyway it's your machine, your money and your time at the keyboard so IMO if you want to ignore the advice of 1000's of really experienced Windows people on this (and other Forums) -- and I'm not one BTW - my expertise is in Linux but I do have understanding of the basic principles of OS design including those old classic mainframe systems from IBM (MVS/SP etc) and just carry on. So in the good words of that classic Texan actor : "I'm Outta Here".

The only way you will know if things improve is to try it and find out. As I stated, it's technically possible. Keep us posted on observable differences if you do give it a shot.

Unfortunately, it didn't work. It seems like it will just overwrite the first one.

That shows that you have a page file on C:\ and it also says that you have an existing page file on E:\ as well. Perhaps before you set your system to self managed, Windows had created a pagefile on E:\.

If you say yes to this prompt, I would expect you would have an 80GB page file called C:\pagefile.sys and and 8GB pagefile called E:\pagefile.sys

I suggest you read this topic from Microsoft concerning pagefile usage and allocation.
How to determine the appropriate page file size for 64-bit versions of Windows - Windows Client
It may help you decide the best options for your use case.

I've never known Windows to create a Page File on another drive outside the OS drive unless told to do so by the end user.

Am I missing something?

If you use vhdx (physical vhdx files) for having your OS on then it's 100% possible (and often normal) to have the page file on the physical disk say D:\ where your windows system is mounted as "C" on say a file on the "real disk" (D:\windows.vhdx) for example.
