I installed Windows 95 OSR2 on my retro PC not too long ago. Usually when I do fresh installs and finish installing all the drivers I look at information about the system's specs in System Properties and DxDiag.

Upon checking out DxDiag, I noticed it wasn't using any of the 1856MBs of page file it always sets up on its own. My PC has 192MB of RAM and nVidia's Detonator 12 display drivers report the OS to be using only about 30MB after starting up and when idling. Even after running a very cache heavy game (Atomic Bomberman) it stays at 0. I'm actually not sure what the page file is. I always see people fight over whether it's temporary data storage or emergency memory to back up the lack of memory when necessary.

I should also mention Windows 98SE on the same PC uses almost twice as much memory and usually consumes 56MB of the page file when idling. Is my config just simply overkill for Win95 to the point that it can rely on the RAM alone or is it an error?

Hi, I remember that Win95 and Win98 had a slightly different caching mechanism.
Windows 98(SE) was even able to execute programs directly from virtual memory (if they were aligned to 4KiB boundaries).
Have a look at the link in Windows 95 OSR 2.5 and 128-256mb ram

I'd say 192MB RAM is very generous for Windows 95, most people probably didn't have more than 32MB was current. Your system doesn't touch the paging file at the moment because it doesn't need it yet.
512MB is the standard limit for Windows 98 to give a comparison.
If you are talking about the system in your sig I would probably just stay with 98SE unless a game requires 95.

Consider running Cacheman, a neat little utility that allows you to tweak RAM and pagefile usage through a simple interface. I use it all the time in my rigs and I've noticed that it does help performance a little bit 😀.

I used to run my PC's with loads of RAM and no page file. without any problems.
Retro gamming PC isn't that demanding really. It's not like back then when you had various software installed like Adobe fast start, scanner software, etc.
Plus its not doing various things like a few hrs gaming, then few hours on the net, then few more in Office.

Now its probably more like turn it on, few hrs playing a single game, turning it off again. with maybe graphics, sound and not much else running in the background.
Now I just leave it at system managed as I have plenty of HDD space and too lazy to change it

Although 192Mb are more than enough for Windows 95, I wouldn't run Windows 9x/Me without page file. Every time I've tried to disable page file on those systems it gave me BSODs. IMHO it's better to put a small, fixed size page file or leave Windows manage it.

(I don't remember when Windows became stable without page file... it was either with Windows XP or 7, but I don't remember for sure)

I've been there too, with 512MB of RAM and no pagefile i got some issues.

I don't want to start a flame war on this, but I don't think there is a point in disabling page file no matter whether you have 32 MB or 32 GB of RAM. It's just asking for trouble.
