My computer only sees 2.5GB. I ordered 4 GB of new ram and replaced the current 4GB and still the same, different ram, same problem.
The Windows 64-bit link that was provided above says "All editions of Windows Vista 64-bit provide increased memory support beyond the standard 4 gigabytes (GB) available with 32-bit editions. Refer to the specific edition of Windows Vista 64-bit to determine maximum memory capacity."
This means that my 32-bit Ultimate supposed to show all 4GB without enabling PAE or DEP. My BIOS sees the 4GB, plus when I had Vista Beta, on this same machine, it worked with my 4GB ram, showed it in Windows and everything, without enabling anything. When the full version came out and I installed the Ultimate, it shows 2.5GB no matter what I did.
If anyone can help, please as I am puzzled.
No, it's impossible to show all 4GB without enabling PAE. See http://blogs.msdn.com/oldnewthing/archive/2006/08/14/699521.aspx for a good explanation of what's going on.
To run the command to turn on PAE, you'll have to run the command prompt elevated.
