Corsair (2x8) DDR4-3000 and -3200 RAM with i7-6700k...Probs.
On a Mini-ITX Asus Z170i Pro Gaming MB...(with latest bios)
Since I completed the new rig a few weeks ago, I haven't been able to get both sticks of RAM running. Enabled XMP in bios...NADA... I have seen this issue raised at many tech sites as I have sought a solution...Bought 16GB of both... My buddy trying to get it running as we speak.
