It is related with increasing hashrate that makes higher difficulty now = 7.43P. last month was 6 or something it grows very fast it means less rewards, also right now fees are low but later swapping 2 starts i think rewards will be better

Is is just me or is Clamore's Ethereum miner been crashing more than usual lately? I suspect is has something to do with the larger DAG files needed, as I can run the same program on another coin such as Expanse and get several days of up-time, but while mining Ethereum I am lucky to get 48 hours before the program hangs trying to restart itself.

I already tried lowering my clocks, increasing voltage, using -ethi 5 and 6 but it doesn't seem to help. My temperatures are quite cool now with winter approaching and all my PSUs are either Evga or Corsair running at only 80% efficiency, so I don't think it is any of those things.

You are missing "-epsw x"
Nanopool has a config generator for the Claymore miner, just click on "Quick Start" and it will create one for you. This is what I get and it works, just put in your details into the grenerator.

Update:

Just did a test mine on Dwarfpool with the setting given below [using Claymore 9.8] and it works OK. I used the example given in the readme file.
