I currently have 4x4gb stick of Gskill 2133Mhz ram in my computer (total of 16gb), and i have two 8gb Crucial 1600Mhz sticks lying around. Would it work if i put two Gskill and two Crucial stick in my computer (totalling 24gb)?
Or would the different speeds and brand cause issues?

My motherboard is the Asrock 990fx Killer and uses DDR3
