whether to go with 4GB or 8GB of RAM ?

thanks :).

I don't understand what you are trying to say... In any case, MrDiaz is correct: the limitation comes from the OS.

32-bit software has the same memory limitations as 32-bit operating systems. However, all the major VM programs are available in 64-bit versions. I have personally used 64-bit versions of VMWare, VirtualPC, and VirtualBox.

The limitation comes from the OS and the software. 32-bit programs running on 64-bit Windows through WOW64 cannot access more RAM than it would be able to under a 32-bit OS.

Well to explain the whole process would take me a while and it can get confusing for you. But in a nutshell:

The software even if its 32bits running on a 64 bit OS, it can access all your physical memory.

To give you a small sample.

App X 32 bits running on 32 bit Windows: The app can't use more than 4GBs because WINDOWS cannot see the memory.

App X 32 bits running on 64 bit Windows: The app uses all your memory because WINDOWS sees it.

Hope that helps.

ok, if the windows 32bit doesn't see more 3.5 gb, so why is it that the same princable aplay in the software ?

if your sure about that, do now how does the memory managment work in windows ?

i don't think your making this up, but please if you know the proper explainination for that please tell, or if you know a good reference for that.

thank you a lot man, you have been a great help :).

I don't have much experince in programing, but I think the program should be 64bit to break the limitation of 3.5 gb, same thing apply for 7-zip 32bit and 64 bit version...

what i am saying is completely hypothetical, it could be wrong or right.

thanks :).

you don't get it at all , I never say the software will access more than 3,5 it's the OS who will do so .... I said if you run 3 software ( 1 in each VM ) who take 2 gb each you need 6 gb to run them, ( 3 x 2 = 6 ) and it's the OS that will handle the 6 gb not the VM and the software.

It doesn't. Like I said before, the application is limited because the operating system is limited.

You can google that

If you not satisfy of the reply you get may be you can be more specific and give us a list of software you gone use ... or is it just an hypothetical question

yes, i do understand what your saying, it basically a matter of triple chanel is giving the performance advantage.

as i said previuslly, because i wasn't deffrentiating between 64bit OSs access for memory, my issue was between 32bit and 64bit version in OSs and software, so I was confused with that.

thak you a lot man you have been a great help

I've always liked canadians, they are nice people. . . I remember when I was in collage I had a canadian teacher and by far he was the best and most caring teacher I have ever had.
his last name was; wenston, he always talk to us about his maserati car back in canada
