If you are on Ryzen you are wasting your time with Verium. You clearly need to be cpu mining cryptonight (Monero, etc). I had a brand new compile of cpuminer-opt and it was recognizing my ryzen with all of its optimizations as far as I can tell. The problem with ryzen 1700 (8 core) is that it isn't what you think it is...its an interconnected cluster of two quad cores. It's hard to explain. I guess there are some very specific disadvantages to this, either in the cache performance or the memory performance via the bus that connects the two quad cores together.
I get your point but people are gonna do whatever they want with their Ryzens imo there are other coins way more attractive to mine with CPU besides Verium even with Intels and it's also a matter of how high is the price going to go in the future.
