I can only install one stick of RAM. I am using GSKILL Ripjaws 16 gig 3200. I keep getting a C5 Q Code on my ASRock B550 TAICHI motherboard. I also tried using Corsair Vengeance PRO RGB 8gig x4 with the same results. I can put one stick in A1 or A2, but cannot put any more than that or I get C5. Sometimes it will stop at F9 then go to 0d QCode. No post at all. I've tried all sticks individually and they all work. Is my CPU bad? Thanks for any and all help.
