I just bought new corsair vengeance 1866 (2 x 4gb) ram for my laptop. My laptop is a hp-e020ca. I just replaced the ram in my laptop with the 2 sticks of corsair memory but when I log on my computer it still says there is 4.0gb (3.22 gb usable). I checked the bios and it also says 4.0 gb of memory but I can't find anywhere to change it. By the way I am running windows 8.1. Does anyone know what's wrong?
