I believe you are going to have more problems than just Photoshop without at least a small paging file under Windows.

Setup a paging file. This has been discussed before in depth by Chris Cox.

Eliminating the Windows Pagefile adds no benefit whatsoever, and ONLY puts you at risk. Your applications are going to try to use ram first anyway and will swap to and from the pagefile when your available resources require it. Turning it off doesn’t "force" Windows to use the RAM as a pagefile. You are actually reducing your available resources.
If you set up a gig of ram as a ram disk, then tell windows to use that, that’s a different (but still dangerous) story.
So the point is, the logic in disabling the pagefile in windows is flawwed, if the intention is to get a speed benefit by forcing it to use Ram.
I have only 0.75 gig of memory in my XP-Home machine. I have tried running with a 2 gig fixed page file and later by letting Windoze manage the size. With Windoze doing the work, the machine ran noticeably better. This seems to indicate that, at times, the file needed to be over 2 gig in size.
As the combined HD and chip memory in this comparison is greater than your proposed "no-swap" set up, I would STRONGLY recommend against it.

There will come a point when XP will require the minimum pagesys and will create one automatically. If XP doesn’t need the pagesys file, it doesn’t use it, so there is no reason/advantage not to create one.
well, i use windows without paging file for 2 years and there was nothing wrong with that. my system is faster and the boottime is shorter than with a pagefile. just don’t really understand why ps display this message if i know what i do. and it’s very funny it doesn’t matter if i click Yes or No buttons when i’m asked about continue loading photoshop7 without paging file. oh, yes. and older photoshop versions didn’t start without virtual memory.
sen – yes, there is something wrong with that: your system is crashing a lot more often than it should. Windows NT/2K/XP needs that paging file.
Disabling the paging file indicates that you DON’T know what to do, and have gotten some bad advice somewhere.
There are many webpages out there with information on how and why to disable the paging file, and nearly all of them don’t understand how the paging system works, and why is shouldn’t be disabled. It’s one of those PC "myths" where people believe RAM is faster than disk, so no paging equals better performance.
Most of the pages I’ve seen about this, also state that not all applications are happy when you disable the pagefile.
If you are really set on this, my advice would be to set up a minimal pagefile, and set the following registry key to 1 to disable paging out your kernel.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
\Session Manager\Memory Management\DisablePagingExecutive
That way the OS stays in memory, and any application that wants a pagefile has one.
Klaas – then you lose the benefit of inactive code being paged out, and thus you have less RAM available than you would with paging enabled.
I think klaas knows that, and issued the appropriate disclaimer. "Who needs a reserve chute. I got one big honkin’ ‘chute and it’s the best and biggest on the market."
Chris, yes, I’m aware of that, just pointing out an alternative to having no pagefile at all.
Personally, I always set up a pagefile (4GB on a seperate harddrive), and let the system do the rest. Using ATA133 7200rpm drives makes any putatitve performance gain by not having a pagefile, rather academic.
Chris, I don’t understand you at all. Please don’t use my words in other way. I wrote i use windoze everyday without pagefile since 2001 and there was NO systemcrash or any problem. Have you read it?
Nobody gave me advices. I tried to customize my system and i disabled the pagefile. I made some tests and i re-enabled it and disabled it and i recognized it’s good. Glory to be god on high!
Sen,
READ the message. It states: "This is potentially dangerous, and offers no performance improvements over running with a properly configured paging file."
If you don’t want to believe it, that’s your choice. But you are not gaining anything by running without a page file. If you don’t want to see the message, I suggest two possible courses of action: either establish a small page file of 16MB as the message suggests, or do not run Photoshop.
thank you dennis but photoshop wasn’t so cheap so if you allow it i continue using it without pf. and i hope adobe will allow me in their next release to disable pagefile without this annoying message. i wouldn’t use pagefile because i experienced my system is better for me without pf.
You have come here for advice on how to do something. You have been told by an Adobe Engineer/Developer/Author that what you are trying to do is dangerous. You still want to do it. Then don’t ask us – we cannot tell you how to do what you want because it is dangerous, not recommended, and no one in their right mind would operate that way.
You have gotten the best advice you will get here, and arguing the point further only frustrates us because you still want to drive the car past the roadblock signs, even though there is a brick wall past the signs.
Ask yourself this simple question: "Why are they saying this to me?"
Ask yourself this simple question: "Why are they saying this to me?"
Or ask yourself: "Why would I keep asking questions of people who won’t tell me what I want to hear?"
sen, I can only say that you have no idea how the Windows Virtual Memory system works. You have been very lucky to have had no problems since you disabled your pagefile, but don’t expect it to last.
Also, don’t expect Adobe to provide a "fix" for a problem you created.
Sen – actually, we wanted to make the message even worse, but marketing and legal made us tone it down.
We know for a fact that Windows is unstable without a paging file. We really don’t want you crashing and then blaming Adobe for your configuration mistake.
don’t understand what is so "terrible" about turning the paging file off. I have been running xp pro fine with it off, using PS7, Avid just about everything under the sun fine. i dont get any error messages, so i wonder why some of you do.
all i know is that xp definitely makes a number of assumptions for its paging file. i have 4gb of ram. now why on earth do i want to have a 2GB page file? (the default) that’s ridiculous. the reason i turn mine off is so all my backups now fit into 1 single DVD.
if you have a lot of RAM, why do you need a page file? even PS can’t use 2GB of it, so if you have enough, the page file in my eyes is just wasted hard drive space, until someone can explain to me why my rig is going to explode tomorrow bec. of it….

If you never run out of resources, you’re fine. But when you do, you need a place to write information to. Where exactly would that be?
if you have a lot of RAM, why do you need a page file
becasue the developer (microsoft) says so. so you don’t have problems, yet. good for you. good luck. you’re going to need it.
You need a paging file because that RAM can be filled up (with BAD consequences), and because you want to USE all of that RAM instead of wasting it on things that aren’t being used at the moment.
the reason i turn mine off is so all my backups now fit into 1 single DVD.
I don’t understand this statement. All the backup programs I use, by default, don’t even consider the pagefile as something that needs to be backed up.
just wasted hard drive space
My pagefile is 4GB (which is way more than it really needs to be), and takes up around 1.5% of my total disk space – I have no problem with allocating such a small amount, for the stability of the system.
I would also recommend that you spend some time reading up on the Windows Virtual Memory system, and how the pagefile works as part of that (echoing Chris’s statement about *using* all the available RAM instead of wasting it).

Yeah… it puts you at risk of having a machine that starts faster shuts down faster, and runs faster in between. It also puts you a risk of extending the lifetime of your hard-drive. You know, if you’r into that sort of thing.
Eliminating the Windows pagefile on a system that has adequate RA speeds up the system OBSERVABLY, which is a hell of a benefit. It onl puts you at risk if you actually do max out your physical memory, but i you’re the type of person who tinkers with their setup to the point tha you’re disabling the paging file chances are you’ve got your finger o the pulse of your computer and you simply don’t do that. If you don’ know what you’re doing, don’t mess with the paging file, or anythin else for that matter.
My systems have 1GB (laptop) and 2GB (desktop) memory, both have pagin disabled, and I have never had a problem. Other than Photosho threatening to break my knees every time I start it up, which i ABSURD. I provide the program with enough resources to handle the wor I ask it to do. To give me a little error-filled lecture every time click on the icon is extreme hubris
