FOR ANY WHO STUMBLE ACROSS THIS THREAD IN THE FUTURE:
After going through the $100 more Crucial Ballistix and Kingston Fury RAM modules only to get the "unsupported memory" flashes, I'm glad I ran across this thread that pointed me to the G.Skill RIPJaws. It works beautifully and, according to the BIOS, is running at 3200 MHz. I haven't confirmed or benchmarked. Just happy it works. On BIOS version 1.4.1 right now. Thanks for the shared info all!
Bought these exact ones (that u/hawkeyeTX referred to):
