I have a Gigabyte GA-970A-D3 motherboard, an AMD FD6100WMGUSBX FX-6100 Processor. I am upgrading my memory. I have 32GB of Corsair Vengeanc CMZ32GX3M4A1866C9 . The m.b. manual states that 1866 MHz RAM is supported if a AM3+ processor is installed (mine is). But when I install the RAM the computer powers on for about five seconds, shuts down for about ten seconds and attempts to restart only repeat the process until I shut it down . Removal of the RAM and replacement with one stick of the origibal (1600 MHz) memory and everything is ok. Then replacing that with one stick of the new memory (1866 MHz) results in the computer shutting down and restarting befor POST again. I would be extremely grateful if anyone can give me a clue as to what is going on here. Thank you.
