Not all ram showing?

[NetsLee]

Hi all, Ive got a custom built desktop with 8GB ram which its showing 8GB being used. Also with checking on Speecy it shows 8GB.

I brought a laptop win 8.1, 64bit, 8GB ram. On the properties it shows 8GB but 6.94gb usable but in speccy shows 7GB. So have I got a faulty ram stick?
