I'm glad it worked for you man!,diime have you tried what I told you earlier about setting the memory according to the timings of the memos? and set to frequency 1866 with the corresponding voltage
Yes, in fact on the Msi board it gives the option of Overclock, and from 1333Mhz I set it to 1866Mhz respectively although I have not done the timings yet, And the final solution to my big dilemma about the Dimm1 and 2 issue, was a little more complicated than it seemed, After the problem with the first 2 dimms it caused me intrigue because being a new motherboard it should not give problems, so I reviewed all the cables (checking for any loose cable or something), Until I took out the CPU, I realized that one of the pins of the CPU socket (lower right specifically) was a little bent which gave as a product no connection to the CPU pin, and therefore when inserting the ramms in the Dimm 1 and 2 it did not recognize them (not even dual channel was possible); so with a needle I put it back in place again and great! Problem solved, now the pc works correctly in dual channel and the processor in normal way, Thanks for the attention of the Forum, anyway the help was very useful to me. Greetings from Chile! 
I hope someone else finds my solution helpful
