I've been using this board for four years now with a single stick of Corsair 8gb RAM at 2400mhz (this RAM is not in the compatibility list)

I have now upgraded to 2x8gb HyperX RAM at 3200mhz but both XMP profiles of 3000 & 3200 don't work and PC does not boot up. JDEC profile of 2400mhz is the only frequency that works.

I have tried clearing CMOS, even to the point of upgrading to latest beta BIOS but nothing has worked.

Any workaround I could try or does this board really not support high frequency RAM?
