High end system, still lowish FPS

Keep in mind that if you don't have a 64 bit system you cannot run with Virtual memory off and that will be needed. You might want to use a tweak program to send virtual memory to another quick disk based HDD. SDD are great for read back but not so great for writing.

Even with a 64 bit system you should NOT turn virtual ram off. Windows still pages memory, and turning vram or paging off could cause lots of bad things to happen or not work properly. Windows should only make use of Vram once memory use is high anyways. It'll then check to see what hasn't been used in a while, or what is inactive, and page it to the HDD. enough ram and it won't need to go through this process, but if you turn Vram or paging off, then that one time it would need to do that it won't be able to and BAM memory error

Also had a big discussion in my college OS class a few months ago about the same issue. There is no performance gain (even if you think there is, there's not. it just does not work that way) for turning of virtual memory,and doing so CAN cause errors. So it's a no gain but possible loss scenario.

Especially with win7, the WMM is very good at what it does.

Just got a new 2500k system with C300 SSD and win7-32 to replace my e8400 with 15krpm hdd for playing newer games. Keeping the same old video card, a GTS250, I get a steady 60fps almost everywhere with no stuttering at all. Occasional slowdown to 30fps happens due to a GPU bottleneck (99% usage reading with GPU-Z), even with all graphics settings at their minimum and 1024x768 resolution. It seems that cpu usage never gets above 48% or so, with 1 thread occasionally hitting 22% usage.

Since I use the machine only for playing games, I only have 4gb of RAM installed, with paging turned off. I've trimmed windows down to the bare minimum, so it is only using about 350M of memory. I've only tested with XIV, but so far no crashes or odd behavior due to no paging file. All the games I play are 32bit, so I'm using 7-32, and XIV doesnt seem to be "large address aware". The XIV benchmark scores about 2% higher with the 32 bit edition compared to 7-64, so I'm sticking with it for now

As far as paging and SSDs go, it seems that most new SSDs have very fast write speeds, so it's not a performance problem to place the pagefile on them. It will cause them to wear out faster, however. If you can stand troubleshooting occasional strange things happening, you can run with paging off. If you only run 1 program at a time with no virus scanner or any other background programs, you probably won't have any problems. I think turning off the pagefile also disables suspend-to-RAM sleeping.

Nothing good can come from keeping paging off. People that say it's good have no idea what they're talking about. DO NOT LISTEN TO THEM.

The page file is only used when A) it needs to be (some apps and sometimes windows itself demands it. Windows will just turn on PF when it needs it and won't tell you). B)You've got a program minimized for a long period of time. It's not active, and doesn't need to hold up space in RAM.

You've got 4 GB, that's not enough to try to run without PF. You will eventually end up with some funky errors/weird behavior (that chances are you won't even attribute to the missing PF).

It's bad mojo, baaaad mojo. A system crash due to lack of memory is a baaaaaaad thing. no bueno. But don't take my word for it, read the article.

and the links he posts to get a better understanding of virtual memory and how windows handles it.

Fact: If you don't fully understand how PF is used by windows, how memory allocation works, how paging works

DON'T MESS WITH IT.

Would you just start pulling wires on a car without knowing exactly what will happen/what could happen?

@Diraco

If you are only running XIV (which isn't large-address aware), and a minimal set of services, 4gb is plenty. I have yet to see XIV use much over 1.2GB, even. Most people want to run more than one thing at a time these days, though, along with a virus scanner, and they don't mess with any background stuff.
So, it's true: the paging file shouldn't be disabled on a machine with a workload that isn't carefully controlled. Best to just leave it on!
