Vista and 6GB RAM

Hi, I want to know if windows vista 32-bit is capable of fully take advantage
on a 6GB 800 bus Memory RAM, I dont care if it doesnt recognize it like a 6GB
as long as it works 100%

Thanks,

It will work but you will only get access to a little over 3gb RAM, maybe as
much as 3.5gb..

If you think I helped you fix your problem give me some rep . Click on

32-bit can access up to 4GB total. That includes the hardware address
area of around 3.2GB usually. You need 64-bit OS to access up to 16GB.

Is that correct? I thought that Vista X86 was limited to 4 GB of physical
RAM. This appears to confirm that:

Unless, of course, your hardware has PAE (physical address extension) in
which case if your OS is PAE aware you can do 64gb on a 32 bit system.
Linux provides that capability and, I'm informed, some of the MS server
OSs do as well.

That PAE is for Windows Server with the appropriate hardware I believe.

32-bit means it can only “see” 2^32 (2 to the 32nd power)
= 4GB.
The computer has to be able to see the (usable)RAM + VRAM + other
devices on Motherboard, etc.
e.g. If you have 1GB VRAM and “other devices” takes up
0.3GB, you will only be able to use a max of 2.7GB (4 - 1 - 0.3 = 2.7)
RAM.
In this case, if you install 3GB RAM, you waste 0.3GB…if you
install 4GB RAM you waste 1.3GB!

i've just posted about fitting 4 gig, and it transpires Vista 32 bit can
access maximum 3.3 gig

If 1GB is being used for VRAM, how is it being wasted?
