Re: T-Rex 0.19.1 NVIDIA GPU miner (Ethash, Octopus, Kawpow, MTP)
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, while
mining ETH I get 28 MHs at 115W ... 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.
I was not able to find any solution to this.
So is there any workaround this issue?
Thanks for your help
Cheers

CheersHere i give you a reminder. My answer for you in the Phönixminer Thread
it is normal for the Nvidia Pascal GPU´s (all gtx 10x0) This cards slow down with every new DAG epoch, same HARDWARE bug as the AMD R9 290 and R9 390 had in the past.
So there is no solution. You can check this, if you benchmark ETH in Epoch 0 and Epoch 400 for example.
My P106 cards do 26mh at the beginning, now i am down to 24mh.
