HI, I've been mining Monero with SMOS for about 2 days, using  miner xmr-stack-amd and Nanopool: My H/s has been all over the place keeping waving between 1000-4000 H/s while I would expect to stay around 3000-3500 H/s. Is this normal?

So I'd like try claymore-xmr-v9.1 instead, but with nanopool. This is the default config string:

 -o stratum+tcp://xmr.hashinvest.net:1111 -u 449TGay4WWJPwsXrWZfkMoPtDbJp8xoSzFuyjRt3iaM4bRHdzw4qoDu26FdcGx67BMDS1r2bnp7f5hF 6xdPWWrD3Q3Wf7G6 -p x -dbg -1

Question,  how can I insert Nanopool? I tried 3 times but didn't work...
