PS. The RAM running at 6200mhz when you've purchased 6400Mhz is standing out for me a bit. I would drop it down to 6000Mhz as that gives you the best performance/stability balance. The 6400Mhz RAM is good to have to give you the cushion, but I still wouldn't push it past 6000Mhz without being experienced with the timings and memory overclocking options under the hood.
