Very very interesting. I'll for sure update here if so.
I tried going over all the timings i could find on here, and what the DRAM Calculator has suggested, and I cannot get any to work manually. But for me at least, A-XMP Profile 1 (2933) is seeming very stable thus far; though I've read a lot of people that state that the Ryzen 2s in specific do a lot better when at 3200, with diminishing returns over 3200.
