promithius Posted October 5, 2010 Share Posted October 5, 2010 Hi all, Gigabyte GA-H55M-UD2H motherboard, TW3X4G1333C9D 2x2GB sticks. Loads okay with sticks in slot 1+2 and 3+4, but wont post in dual channel in either 1+3 or 2+4. Fans spin for 8 seconds then system shuts down and starts up again after 3 seconds in an endless cycle. Default BIOS settings. Help? Link to comment Share on other sites More sharing options...
