I have point my two Antminer S2 to nicehash but as I see it get 20-30% rejected
17************ 450.97 214.75 (32.26%)
18************ 645.05 175.92 (21.43%)
Miner has latest firmware and diff is regulated by miner itself.
I have try whit --queue 0 --scan-time 1 --expiry 1 but still have same results.
Can rejected rate be reduced somehow?
Thank you
Unfortunately AntMiner S2 is know to have issues with our stratum servers due to a specific version of cgminer used in it which has a bug regarding handling of extranonce2 (as used in our stratum servers). You can try to use stratum-proxy and see if you get better results. btw: other Antminers (S1, S3, S4, etc.) are known to work good
I have try with proxy as described on your site with no luck, this is an error that I see in terminal where proxy run:
2014-10-24 10:28:00,669 INFO [Grizzly-worker(1)]:strat.mining.stratum.proxy.worker.GetworkWorkerConnection - REJECTED share (diff: 512.0) from x@Getwork-/192.168.0.209 on Nicehash SHA256. Booo !!!!. Error: JsonRpcError [code=23, message=Share above target., traceback=null]
I also try with bfgminer proxy but also it get some errors and hr is about 500gh/s for two S2 which should be 2th/s.
So conclusion is that there is no way to mine with an S2 on nicehash without large number of rejected shares?
