32 bit programs 3 gb each?

If i am running several 32 bit programs in windows 7 64, do they all share the first 3 gb (or 4), or can they each access the 3gb max for 32 bits.

a
thanks

Are you saying that these programs need 3GB of RAM each in order to run? That would be unusually big. What are those programs - games? In any case, the system loads them into RAM one after the other and if all RAM is taken, it pages out some other stuff. That will, of course, slow your system down.

so for instance premier elements is a 32 bit program. it can only use 3-4 gb. But if i am also running photoshop elements organizer, and photoshop elements, each is 32 bit. so you are saying each can use 3-4 gb of memory, that a 32 bit program could use?

Apps will share the available memory in accordance with Windows Memory Management. If physical RAM is unavailable, the pagefile will be utilized.

so in a sense, 32 bit applications may run faster on a 64 bit system because a 32 bit sytem with available 3.? gb, must share that with windows, the applications (such as adobe premiere elements), and task manager, .....

but with 64 , it can grab the max that 32 bit allows...

A 64bit system will run better if you have more than 3GBs of RAM. It does not really matter whether that is a 32bit or 64bit program.

Actually, if you are running a 32 bit program in windows, it can only use about 3.5 gb. even if you have 96 gb, it will not run better then if you have 4 gb.

I think you are confusing a few things.

It's really only 64-bit apps that benefit from 64-bit...and only certain ones that take advantage of really large datasets. While I'm not against running 64-bit, I don't expect most people will see a lick of difference from a performance standpoint.
