I have same board also with 16gb of same memory, running ok here.
Memory volts was upped to about 1.56-1.57 volts, & tweaked VTT slightly.
Before my nephew had the pc, I use to run 32gb of XMS memory again without any issues.
Any one local you can borrow from some memory or try another cpu to rule any problems.
Can't understand why you are having so many problems, time to start from scratch I think, clear the CMOS, remove overclock, etc, & start again in stages.
Get the memory working stable first, don't be so aggressive with timings, then look at o/c in stages, might be cpu related.
