My setup is 1x 1070 and 1x 1070ti and I manage to have 2,3/2,4 MH/s for noescrypt algo which gives me an average of 0,0011 btc per day.
I only mine neoscrypt 'cos it is the most stable and profitable in the 24h between all algos I tried.
The only problem is that it often happens that the miner gives no shares for 5-6 minutes and it lower my hashpower and earnings a lot.
I use ccminer KlausT, and when I start it, it sets the stratum difficulty to 4096 (which is supposedly too high for my setup) and after 2 minutes of no given shares it always lower the difficulty to 2048.
Now the 2048 difficulty works sometimes, but other times it gives me no shares for 5+ minutes, and the miner doesn't lower the difficulty under that parameter, preventing me to give more shares and stopping my earnings for 5 minutes or more.
Here some examples:
Can you tell me if it's normal or do I have to do something to get the best from my rigs and not wasting time with no shares?
There is nothing you can do. Some of the difficulties have a min. difficiutly and you can't lower it.
XMR is another one that has a very high difficulty and if you are only mining on 1 or 2 GPUs it will be a while until it finds a share.
Either way, overall it should average out and you will make the same amount of money anyways.
