I just got done with almost the same build. I am having some of the same issues with the RAM. I cannot get it past 2133. CPUID and BIOS say its at 2666 but the command line check says 2133. I have not messed with the timings at all but they are slower than what the memory is capable of. I know just enough about overclocking to get myself into trouble so any info you guys might share would be extremely helpful.
