Hello guys... I need some help here.
I switched my gpus (gtx 1070 8gb) to ETH after a long time, and what I see is some strange behavior. It seems that hashrate is low, and memory overclock doesn't have any effect.
What I was able to google out is that apparently when there is more than 50% of 1070's gpu memory utilized it starts to behave strangely. When I try mining ETC everything is normal (sure ETC have DAG size much lower, after fork).
So mining ETC I am able to get 33 MHs at 90W with underclock and undervolt core and overclocked memory as much as possible, while
mining ETH I get 28 MHs at 115W (overclocked nd undervolted core, little overclock on memory) ... you see my despair
... also mining ETH overclockin core have positive effect on hashrate, while overclocking memory doesn't have any impact - which is not normal for ethash.
It happens the same on windows or linux (hive os), the same on all miners (lol miner, phoenix miner, t-rex miner ...)
I was not able to find any solution to this.
So is there any workaround this issue?
Thanks for your help Wink Cheers

It is, unfortunately, normal behaviour for Nvidia 10x0 series. Growing DAG is significantly reducing hashrate. Nothing to be done here, except increasing core frequency/voltage until it's unstable or too hot... Good hashrates are basically gone on these cards. Even 1080 Ti was doing 57 MH/s with eth pill and now it's down to 45-47. What I did was reducing memory OC but increased core clocks a little (1920) to find sweet spot between hashrate/temps/power comsumption.
Coming back to lower DAG size will bring hashrates back to normal, hence if you want to see numbers higher the only solution is to mine ETC or other ethash coins with small DAG.
