I am trying to use 2 sets of F3-14900CL9D-8GBSR on a GIGABYTE GA-990XA-UD3 with an AMD FX-8120 3.1ghz. when I adjusted some of the timing settings to match the given specs the board will not work. The memory functions on the board at 1333Mhz with the boards default settings. Can anyone assist me in getting the settings right to function at the full 1866Mhz?
here are the settings available for adjustment. (not the current settings)
