also is it a Ryzen 5 1600 cpu that you have? in that case your hashrate is abit low.
~400 H/s is a bit low for a Ryzen 5 1600? That's better than I'm getting with mine (370-390 H/s), though I did turn the devfee off because it kept failing to connect to the devfee pool and was spending way too long on the issue.
*If* I can get 400+ H/s *and* the devfee server isn't an obstacle I'll gladly re-enable paying the devfee.
