I switched my ryzen 1700 over to verge. Scrypt algo on mph. Not sure yet if it would be better to use lyra2v2 on another pool.
would it be a rooky mistake to ask you to run nicehash or its benchmark to see what you could mine best with your CPU?
...if you're not under linux of course...
The only CPU benchmark for Nicehash is Cryptonight algorithm.
According to the calcs zcoin, electroneum, and monero are all able to turn a profit with a ryzen CPU. Not big money obviously - $25-40/month.
Stock clocked ryzen 1700 gets about 650 kh/s lyra2z. 500 h/s crytponight. Power draw is under 100w. Do the maths.

Yes lyra2z and cryptonight are profitable algorithms for Ryzen CPUs. AEON (Cryptonight-Lite algorithm) is also a good choice. You could try Magi, Verium, or Biblepay as well.
