I have 16gb of ram installed in my computer however my computer says i only have 8gb of ram working. I went to bios to check it out and the computer is detecting the sticks of ram but it is not using them I guess. I would love some help with this. I have some pictures to help explain what I am talking about if they are necessary. My Mobo is an Asrock Z77 extreme4 and I have 4 sticks installed
