I lost 1 gig of mem according to Vista Ultimate

[David B. Mathews]

My new Dell came with 4 gigs of memory. Belarc Adviser says I have 4 gigs
and a couple other NON Microsoft programs says so too. But why does most
Microsoft program say I only have 3 or in the case of the program that tells
my performance which is 5.9 for everything say I only have 2.75. How do
they come up with their reasoning?

Windows Vista 32bit only recognizes up to 3GB of memory. Something to do
with the 32bit architecture. I don't fully understand it myself.

Cheers.

I have 4 GBs of RAM in my system, and I’m running a 32-bit version of
Windows Vista, but I don’t see 4 GB of RAM in the System Information
Explorer, why?

The system memory that is reported in the System Information dialog box in
Windows Vista is less than you expect if 4 GB of RAM is installed:

If you search the newsgroups you'll see this issue is touched on and
explained many times, and a simple Google search will give you right at the
top of the list, this link.

Explains the reason you're not seeing the full four gigabytes in Windows 32
bit.

Thanks to all for your answers. As I have only had this new Dell for 3
weeks and only been using Vista for this long I was not aware of this

A 32-bit machine has a 32-bit (4GB) memory space. This space must be
used to access video memory, BIOS, and other things as well as RAM.
Once the other things are taken care of, the remaining address space
is used for RAM. See http://members.cox.net/slatteryt/RAM.html
