I have a asrock x79 extreme6 that wont post brings up codes d6, 60 but stays on 61 I've tried three different types of ram 1. g.skill Sniper 1600 2. G.skill ripjaws z 1866 3. G.skill trident x 2400 which are all DDR3 and the tridents are compatible by asrocks website. I've tried all dim slots with just one stick with all three types no good. It was running on the snipers but hadn't use the pc for ages and now i have this problem. Would greatly appreciate anyone's help
