Large Address Aware

it"t related to a game!can i still make the question?

Let me guess, you want to know if flipping the LAA bit will help on <insert game here>? The answer is "I don't know" unless it is listed in the original post under the list of applications known to benefit from being made large address aware. In short, you can try it and if it helps, great; if it doesn't help (usually crashes on start or not long after), set it back to the way it was and it will be back to status quo. There's really no harm in trying.

Without the /3GB switch functioning, however, enabling the LAA bit isn't going to help much. It is really time for a computer upgrade. Most new systems today come with at least 8 GiB of RAM and a 64-bit operating system. Windows 10 is coming out July 29 too.

I think you are right i need a computer upgrade instead of making questions about a game that i know for sure that doesn't work so thank you all for your advices!!!

I'd forgotten about this app, since I run solely with 64-bit arch now. Still an excellent job by Ford. thanks mate :)

it still helps a lot, since all of... well, still no games are 64 bit.

no stress, i'm still surprised by how essential this tool is... you'd think game devs would figure it out by now.
 
It's buried in Visual Studio so it's always an after thought which they are reminded of when forums light up with "try doing this to fix your crashes!1!1!11!"

I will show you a 32bit OS with far more than 4GB of RAM in use, maybe 16GB if I can get the RAM. I'll also disable the pagefile so there is no confusion.

You're going to use a 32bit application on 32bit windows, and display that app utilizing more than 4Gb of ram?

Euro Truck Simulator 2 is also updated to 64-bit ;)
 
If he produces some data there are things to discuss, but 'til then he's a random internet dude claiming magic.
 
The address space is 4 GB. By default user space gets 2 GB and kernel space gets 2 GB. All the /3GB switch does is change this layout. Phil, you don't make sense.
 
eh..I try every game I use with cff explorer.
If it works, it works.
If not,I made a copy :D
 
The article is talking about how the OS is handling virtual to physical memory mappings - it takes up address space. By lowering the size of the kernel space, you lower how much physical memory the OS can handle.

Ford look, this is what we use in IT we do not go to MSDN, all major companies have in house best practices. Here 's one from Symantic on the 3GB switch.

This wasn't written for servers.

The advice was given to a person who had an application that would or could benefit from becoming large address aware, the second part to this is the operating system, Windows XP X86 needs to allow the executable access to the 3GB of memory, and yes, everyone understand that when you shrink the systems memory fewer Page Table Entries are available, but this doesn't matter on Windows XP as they are static and assigned. Obviously the user ran into a issue where the resources consumed by the devices, kernel, and OS exceeded the memory available in the last GB of RAM, and only preemptive tuning could prevent this, had the user forced /USERVA without being aware of how much memory the system was actually needed the same issue would have happened.

I updated the original post a few days ago (before you posted) recommending only tweaking with at least 4 GiB of RAM installed (previously said ">2 GiB") as well as providing undo instructions that I thought were always there (and apologized for the mistake). Until it happens again (it took five years for it to happen to @Cristina), I'm not concerned about it. On top of that, there's enough tech heads at TPU to help should the worst come to pass (as demonstrated).

I have purged all of my off topic reply posts since Cristina first replied.

PAE was the solution to a Server-needs-more-memory problem on x86 up to 2005 when AMD64 debuted. If you have >4 GiB of memory installed and are running an x86 operating system today (exception: virtual machine), you're a fool. It may have been helpful advice a decade ago but it isn't today.

Yeah I agree, but who does these days...it was helpful back then but not now.
PAE was a little irrelevant here in this little discussion too, I was trying to paint a bigger picture for people.

It's the increaseuserva/3GB being bad which was my point anyway, hope u got that.

Also I forgot to tell you, in 64bit Windows LAA operate in 64bit compatibility mode. This means once LAA flag is set on 32bit apps they will use 4GB. Nothing else needs to be done. :)

About Cristina's crash. I don't know what she did, but her computer did not crash because of this flag.

Why should he leave? He's given helpful advice. And quite obviously knows more about this than anyone else who's opened their mouth in it....INCLUDING AND ESPECIALLY THE OP!!! Whom way failed to do his homework first.

Your hardly being helpful, this thread was posted five and a half years ago, to say that the OP didn't have a clue what he was or still is doing is hardly contributing to anything, apart from of course flaming, if you have nothing more constructive to add might I suggest you move on.
