To all of you wondering why you're getting 15 mh/s on ethereum out of the box with your 1060s 3G:
You got unfortunate enough to get gpus with Hynix memory which is very crappy for eth mining, instead of Samsung or Micron.
I got 4 MSI GTX 1060 3G ITX OC just yesterday and was very disappointed to see the Hynix name.
As far is I know there's no way to increase mining rates to Samsung levels, but I'd love to be proven wrong.
Palit Storm X GTX 1060 3GB out of the box all settings at stock making an impressive 18.9 mhash and if I overclock it it goes up to 22 mhash with a 650 boost memory clock. I hope you enjoyed being proven wrong.
Mine has Samsung GDDR5 memory though so that's maybe the reason why it performs better.
thats exactly what he just said..
I also just purchased 6x ASUS DUAL OC 3gb cards and they were all hynix. stock 15mh/s. OC'd (+500 mem) 18.5 best ill get.
my gigabyte card does 23... fuck asus
