Vista memory x32 vs x64 what are utlilized the limits?

[msny]

Does anybody have any links handy that explain the
various memory models avaialable for all versions
of Vista?

Our netword admin thinks that Vista32 will utililze
all 4 gigs of memory, but I thinkts only 2 gigs, right?

Either way, I need something that verifies the usage for him.

Thanks!

32-bit Vista is able to address 4 GB of memory space. Devices like video cards, sound cards, etc. are all addressed through the memory bus too (in x86 systems) through the technique of memory mapped I/O, so how much RAM you are able to utilize will be limited by the other devices. However, 32-bit Vista is limited by an upper bound of 3.25 GB no matter what, I believe. x64 Vista Home Premium supports 64 GB of RAM I believe, and the higher versions support 128 GB.

Home Premium is actually limited to 16GB, but that's still way more than any regular desktop needs right now...

Right now anyway. I don't think Microsoft anticipated people running 4 or more GBs of RAM on Windows XP when it came out.
