How much memory can Vista handle? Is there still a 3GB limit on memory for
Vista.

Do you need to have Vista 64Bit to be able to utilize more memory?

Thanks
Jasper

about 3.2 to 3.5, actually.

For vista, yes. For other OSs, no. For example, 32 bit Linux and some of
the ms server versions will handle up to 64gb.

That begs the question, why such a huge differential and the limited
capacity in Windows Vista in comparison?

PAE (see wikipedia - page address extension) is a methodoloty for
allowing 32 bit systems access to larger than 4gb address space - though
still only 4gb at any given instant. Think page swapping, if you know
about that.

The MS desktop systems do not support PAE - their server systems can, and
Linux does (desktop as well as server).

just plain meanness, if you asked me...

Typically, install 4GB for the 32-bit versions and as much as you want for
64-bit Windows. Some 32-bit OSes can be specially configured to make use of
up to 64GB of physical RAM, but out-of-the-box you will want up to 4GB RAM
for a machine running 32-bit Windows and a bigger wallop for a machine
running 64-bit Windows. I only installed 8GB.

Vista can handle many (many) gigabytes of memory--as much as the processor
and motherboard can handle. With 32-bit processors, the limit is set by the
address bus of the motherboard, how RAM is managed and shared by the video
card and how the hardware mfr. has dealt with these issues. Yes, this means
most 32-bit systems can't handle more than 3.5 GB of memory. The upper 500
MB is saved for use by the video card.
In my 64-bit systems, I have at least 4GB and upwards of 8GB in others--all
were running Vista or a derivation in a server OS until I migrated to
Windows 7. I could install more but my motherboard configuraiton and budget
(and needs) say otherwise.

Not really. When XP, and even Vista, were developed, RAM
was still expensive, and 4GB desktop systems were rare. The
64 bit versions of both Windows were available for more
powerful systems, with higher memory. Vista Ultimate has
both 32 and 64 bit versions in the package, and for other retail
versions of Vista, 64 bit has been available for basically the cost
of shipping. All retail versions of Win 7 will include both 32 and
64 bit versions. Also, by the time of Win 7's release, the majority
of PC's and laptops will ship with 64 bit installed, except for low
end units. From what I have seen, even now, most mid-range
and above laptops come with 64 bit Vista.

Care to share where you found that tidbit?
 
What variety of Vista are you interested in as there are at least two major
groups 32 bit and 64 bit. I'm running Vista Home Premium X64 with 8 gigs
but I now see systems for sale that offer 16 gigs of ram. Server versions I
believe offer 64 gig capacity. I don't know if regular 64 bit Vista can
handle that or not.
 
That is a lie of omission ray...the worse kind of lying. You're
referring of course to Vista x86, the 32 bit OS, which you failed
(purposefully?) to state.
Vista x64 will recognize all of the RAM you can currently install on a
desktop/laptop computer.

Geez frankie, you need to get your glasses checked. OP asked "do you need
to have vista 64bit to be able to utilize more memory" - I answered "for
vista yes".

Please explain to me how that is a 'lie of omission'.

Are you running a lot of virtual machines? I can't find any other way
of using more that 2 or 3 gigs in a non-server.

You've got to remember that things are different in Frank's World.

Figures. You couldn't find your ass with a road map and a flash light.
