im testing a antminer s2 in your plataform, but i got around 320 gh rejected and i have a difficulty of 2048. How can i make it work betteR?
I'm seeing the exact same thing with my S2. I have S1s and S3s cranking away at Nicehash with no issues, but my S2s get very high reject rates and huge swings in hashrate. I'm running the latest firmware and I did try running the stratum-proxy solution Nicehash recommends. I've played with difficulty and everything else I can think of but can't seem to get stable performance from my S2s at either Nice or Westhash.
try --queue 0 --scan-time 1 --expiry 1
it helps, but my s2 usually has about 100ghash of rejected
Thanks! That one change has made a bigger difference than anything else I've tried. I'm getting higher hashrates now but still see around 15% rejects at the top end (175 Ghs) with an average around 100 Ghs rejected. I'll play with those values and see if it gets any better.
