I just downloaded TweakVisa onto my new Asus notebook. It has 4gb memory, but TweakVista reports that it has only one! (Not even close!)
Incidentally, Everest and Vista Computer Properties think I have 3gb and SiSandra thinks I have 2gb.
So far three strikes--but there is a winner...the System Bios recognizes all 4gb. (According to Asus, this notebook can handle up to 8gb.)
So, in order of accuracy:
1. Bios (4gb .. correct!)
2. Everest and Vista Properties (tied) (3gb close!)
4. TweakVista (1gb not even in the ballpark) The big loser!
BTW: I am not sure if I will be able to get back here if anyone asks questions. I am not happy with all the stuff that Stardock installed onto my computer, and I intend to remove it all right away.
