Looks like Zen+ is a little more picky with memory than my old 1700. That was solid at 3600.. but even 3466 is giving me random issues. Time to wait for a BIOS update...
It is (afaik) however it's also more sensitive to timings, GamersNexus did some testing and found that if you just changed the four main timings and left tertiary timings on auto it lead to big performance differences, i would imagine that also means some boards are over-egging those tertiary timings when left on auto with certain memory and could be causing problems. It's either something you could probably sort out yourself with a ton of faffing about or wait, like TheMadDutchDude plans to do, until hopefully your MoBo vendor issues a BIOS update.
