Why does Windows see less RAM than CPU-z ?

Running on a Dell Studio XPS 8000 I have Windows 7 Professional (64bit) and there were 2 * 1GB and 2 * 2GB sticks and Windows reported 6GB. Life was sweet. Then One of the 2GB sticks failed and was removed. Windows was reinstalled but only 3GB is shown as present in Windows. CPU-z however reports the full 4GB. I would appreciate an education.

I don't know how it was before, but is there memory being shared to the graphics card?

There is a discreet video card: NVIDIA GeForce GT 220

I would suggest swapping the modules around in this case. As for why windows is reporting it like this and CPU-z is not.. i could not be sure.

1. More than one stick failed, CPU sees cold stick body.
2. Motherboard problem- the slot itself failed, all sticks were functional.
3. You installed 32 bit OS (lol).

32bit OS was my first guess, but screenshot says otherwise. the 'lol' in your post means you probably knew that too!

The next post would be, "Why under system it shows 64 bit while it acting like 32". No, I did not see the image- saw it now. On my 32 bit systems I have 4 Gb on 2 computers and both show different number. I looked it up while ago and noted that many people reported the same thing. Not sure if it applies to 64 bit. May be consider to add more memory and see what happens. My XP system shows all 4 Gb, Vista shows 3 Gb out of 4 physical.
