Which Windows 7 OS allows me to use more than 2GB per program?

Hello,

The Dell Inspiron 546 in my signature below currently has Windows 7 Home Vista Premium x64 installed with 4GB of RAM. It has been proven through benchmarks in the programs that I specifically use that I will see a benefit in rendering large video files if I have more RAM. There was one site that listed which operating systems allowed the usage of more than 2GB of RAM per program, but I can no longer find this site. I found a link to Microsoft that only tells me the limits of the overall system usage, and not the limit of a single program such as Sony Vegas Pro or WinAVI.

I will be building a PC soon with 12GB of RAM, and need to know which versions of Windows 7 will allow me to use the RAM to the fullest.

Thank you.
 
The operating system you have. I believe it is 16GB max. There is no limitation on memory used by programs except in 32 bit applications or operating systems. Is the application 64 bit? If the application is 32 bit I believe it can use up to 4GB on a x64 OS if you have it set to large address aware. I don't know how to do that though.
 
I misread the question, but bigdogchris is correct about memory usage per program.
 
Yes I think bigdogchris is correct. While a 64-bit OS can use more than 4GB of RAM, the program itself has to be a native 64-bit app to be able to use all that RAM. If you're unsure if your app is native 64-bit, just open your Task Manager while the program is running, go to the Processes tab and look for the executable. If it is a 32-bit app then you'll see a *32 next to the process.
 
OK. I'll try and see if I can get her video editing program to the 64-bit version. I think she has a free upgrade for it.

I knew that her work was a resource hog, but I just upgraded her to 4GB and Windows 7 yesterday, and I looked at the task manager today and she was already eating up 3.2GB with just Sony Vegas, Photoshop, and Firefox. UGH!

I've limited firefox not to exceed 384MB anymore, but it'll take a while to fix the other two.

How will you able to limit firefox to not exceed 384 MB of ram usage? Believe it or not firefox is ram hog and really there is nothing you can do about it. I have tried.

Are the programs that 64 bit just not say *64?
 
32-bit programs will still be limited to 2gb even on a 64-bit OS. They can access up to 4GB if they are Large Address Aware but that isn't a setting you can just adjust yourself.
 
You can set a program to be large address aware yourself. Microsoft offers editbin to do it.

There is just a note, and that is some programs might crash because of it.

I would never in a million years, set a program Large Address Aware that the vendor didn't set themselves. It is a timebomb waiting to go off. (I mean that, it can crash at any operation in the program, and if you didn't save, Boom)

(I believe Photoshop is already LMA)
