4GB RAM installed, but see 3GB...

Presumably this is old business, but not for me.

I have a Sony SZ670 with the T7700 at 2.4GHz and 4GB of
RAM installed, and Vista Business. 32 bit.

Computer > Properties shows RAM at 3070MB.

Is it actually USING only 3GB? Is there a reason and a
way to improve utilization?

???

What you are experiencing is normal. Don't worry about it.

Alias

look in your BIOS when you restart machine and verify that 4GB is
recognized.

Here is a great explaination:

Basically, it is a 32 bit limitation.

Unless your using the 64 bit version of vista (or XP)
you'll only be able to use 3GB.
That is the limit.

Yes, it's only using 3GB. No, there's no way to improve it (although
for most people, there would be no difference in performance between
having 3GB and 4GB).

All 32-bit versions of Windows (XP as well as Vista), even though
they have a 4GB address space, can only use *around* 3.1GB of RAM.
That's because some of that space is used by hardware and not
available to the operating system and applications. The amount you can
use varies, depending on what hardware you have installed, but is
usually around 3.1GB. You got a little more than the average.

Note that the hardware is using the address *space*, not the actual
RAM itself. The rest of the RAM goes unused because there is no
address space to map it too.

Thanks for the info and the informative link.

I'm very satisfied with the way this unit is working,
but of course thought there might be... more.

Worry about it!
Some drivers cannot work reliably with this configuration.
If you use 2G you probably will have no problems.
Add another 2G and get ready for problems until the stupid peripheral mfrs
figure out how to deal with Vista or MS fixes it all.
Vista is stupid about RAM and drivers and does not seem to know what to do
about it.
I had one driver supplier admit that their problems were totally due to
Vista not knowing how to adjust memory when over 2G is used.
This is still not resolved on my PC with 4G running Ultimate.
I started with 2G and had zero problems with a fairly complex PC.
I decided to add 2G more and all hell broke loose.

There is a tool/hack/way to get all that ram to work in Vista 32 I
believe. Look around. There is a mod for it, but generally speaking the
32 bit edition is limiting in ram, perhaps three gigs. My honest opinion
is if you have that nice pc get the nice OS, Vista Ultimate.
TigerDirect.com sells it for like 1/2 price and I have been loven it, so
far for months. Give her a shot. Its worth it!

I like Vista Business, and can certainly buy Ultimate if
there's a reason to do so. What are the advantages? And
can Ultimate somehow recognize 4GB of RAM??
