The issue with 32 bit is that it can only address 4GB. Hardware uses space
from 4GB down, so depending on the hardware, you lose anywhere up to 1GB
from the available 4GB Windows limit. 

 

64 bit still has the same issue, but from 128GB which is a Windows limit on
Vista, probably the same for Windows 7.

 

Server 2003 can address up to 128GB (4GB for SBS) in the 32 bit edition or
2TB in 64 bit. Funnily enough, Server 2008 can only address 64GB in the 32
bit version. That must really annoy people. Who would ever need 64GB Ram? J

does windows 7 see all the RAM?

The real question though is how much benefit you actually got from that
extra 0.5 - 1GB ?

 

I'm guessing not much.  Not really.  But if you've got a system equipped
with 6GB or 8GB. at that point 64-bit makes perfect sense (and if you're the
sort of user that is loading a 4GB system so heavily that the extra 0.5-1GB
*does* make a difference, you're probably the sort of user that would like
6-8GB of RAM anyway and you've already long since moved on to 64-bit).

 

But at 4GB I really don't think there's much in it, so whilst there may not
be a specific reason to use 32-bit, there's also no great compelling reason
to use 64-bit either, and a few *potential* reasons not to (lack of 64-bit
support for XYZ, where XYZ varies from individual to individual) potential
complications when running (some) 32-bit software etc etc.

Vista 32 will never see all 4 gb due to mapping issues with the video card
etc.  Under Vista 32, I got between 3 and 3.5 gb available on my laptops.
Vista 64 got the lot.  How much you lose depends on your video card memory.

aiui if you've only got 4GB of RAM then I don't think 64-bit is going to
make that much of a difference.  Of course, if you have the capacity to go
beyond 4GB of physical RAM and the intention to do so, then 64-bit might be
worthwhile.
