I see.
I just got my new ASUS STRIX ROG GTX1060 6Gb with Samsung memory.
Still playing with OC but I managed to get 23.598 MHs ETH at 75w usage.
This card can reached 25 MHs but I was not able to get stable OC settings yet.
Will try tonight.
Just an update, I managed to make it up to 24.4MHs ETH at 60C Temp 77w power usage (nvidia-smi.exe) on this card.
My Micron memory ROG card only yield 24.01MHs ETH at the same 77w power usage but 55C Temp.
Now my Palit Hynix card is mining at zcash right now and I only managed to make it at 90W power usage, 66 Temp @ 300sol/s.
I would have mined it at ETH if it can only go further than 19 MHs.
