a while back when vista was released a bunch of people here said that vista 32 bit was able to use over 4 gig ram. is this true? i still believe 32 bit won't use more than 3.2 gigs wheras 64 bit will. just want a final confirmation. thanks
 
Read this :)

Windows memory manager in the x86 variants of the operating system is restricted to 4GB of memory due to the limitations of the 32-bit hardware. The 32-bit address range cannot be filled exclusively with RAM, because the physical address space needs to be divided among the hardware in your system.

Due to these limitations, 32-bit Windows Vista will only be able to address approximately 3.5 GB of RAM. However, there is a way around this. One that will enable you to enjoy the full extent of 4 GB of memory. Still, you should be aware of the fact that in the vicinity of 4 GB of memory, 32-bit Windows Vista will not manage RAM efficiently.
If you indeed want or need to use more than 4 GB of RAM, then you should consider switching to 64-bit platforms. The 64-bit editions of Windows Vista deliver support for as much as 128 GB of memory, so you can go all out.

But as far as 32-bit versions of the operating system are concerned, all you have to do is access cmd via Start, then enter cmd in the search bar and make sure you run it with administrative privileges. Next simply type "BCDEdit /set PAE forceenable" and hit enter. This command will enable Physical Address Extension (PAE) in 32-bit Windows Vista, and the operating system will be able to address memory larger than 4 GB. Via BCDEdit, you will be able to configure the boot configuration data store via the command line.

Indeed it is. Someone actually figured how to hack the windows kernel on xp, and made it rune in 36-bit mode.

Micro$oft but the limit on xp because at the time, their enterprise versions of windows were 32-bit, and could use more than 4 gigs of ram.
 
Nevakonaza, does the article you gave really work? ( i'm talking about the bottom part ) and you can use more than 4 GB ram in 32-bit versions?
 
with 36-bit hack, supposedly you can. but it probably won't work and it's also very dangerous to download large suspicious files over the internet :)
 
ok answer this. lets say hypothetically you're using vista or windows 7 in 32 bit and you install 4 gigs. when clicking on properties do you see 4 gigs? from this thread i understand that 32 bit OS WON'T USE over 3.2ish gigs of ram but will the computer tell you it has 4 gigs + installed?

correct.
 
im starting to get confused with all this 32 bit limit

does using the pae switch actually work? will it allow the os to see more than 4 gig on a 32 bit os, i was reading on the microsoft website that it will work but it may create instabiltiy due to drivers for home computers being written for 32 bits not 36 bits

has anyone tried using PAE? if so does it work and utilize all ram or does it just allow you to see that there is 4 GB (or more) installed

thanks

No, you won't see all 4gigs. The OS will not recognize all of it. You will only be able to see it in your BIOS.

Btw, I made Ganzey's sig!!! Woot!!
