GA-H97-D3H i wish to xmp the 1333 mhz with same memory sizes only diferent mhz, or even xmp the 1600 to 1333, so they both be equal would be possible?

If you have two different DIMMs with different XMP profiles, then XMP probably won't work correctly. You will probably have to hand-tune the DIMMs and choose the worst settings of both DIMMs to make them interoperable.

Whenever I used two different memory sets at the same speed the XMP profile was determined by the first DIMMs. I will usually try the slower memory profile in the first slots. At present I have xmp-4000 19,21,21 first and xmp-4000-19,19,19 second and raised voltage to 1.4 on the Dimms.
