i understand what you mean but it drops 0.03 in 1 day?? and the calculator on https://etherscan.io/ether-mining-calculator showing for 53Mh/s 0.404 ether while i barely get 0.35 ethereum!!!
Calculators are just for guidance because they always assume optimal conditions. Real life earnings depend on other factors, mainly the pool's luck finding blocks.
Therefore, it's absolutely normal to have real earnings a bit lower than those calculated by any simulation algorithm
any suggestions. i really burnt trying
I'm getting roughly the same with one of my rigs mining at that speed at ethermine pool. I left Dwarf's when they started having serious and systematic problems. A smaller pool is an increased risk because it can take two or three days to find a single block at that means you earn nothing during that period.
The choice between Claymore's or Genoil's depends also on your hardware, drivers, etc.
Finally, keep in mind that it won't make sense to compare today's result using Claymore's with the result's you got with Genoil's 3 or 4 days ago. In the meantime ETH difficulty increased and your earnings would have decreased regardless of the miner you used.
last question (i know it should not be in this thread) but i have an external fan working for my rig while the gpus fans at 100% and temps are 66-60-60 but if i switched off the external fan and started the miner it will restart my pc after 10 second im think before loading DAG. and that happens after i installed a new power supply, 16-16 cable and 16-1 raiser can the raiser cause that if the fan is off??
I know this doesn't answer ur question but, i'd lower the fan speed its perfectly fine to let the gpu's get a little warmer (about 75oC max) the lower fan speed will extend the life of ur fans, while the additional heat won't hurt ur gpu's.
that leads to same 0.35 i wish to add one more 380 or trying the new 480 soon
