If your 1060 has Hynix brand memory, that is normal hashrate.
Samsung goes to 24-25-26mh/s Micron to 23-24mh/s
That dependancy is specific to 1050Ti and 1060.
Woah don't oversell the 1060.
Even with a Samsung memory, hashrate will most not likely reach anything more than 24 MH. Heck, even if you have a Samsunng P106-100 (mining edition GPU based on the 1060) it would be hardpressed to reach 25 MH. I mean feel free to prove me wrong with actual screenshots or videos but until then, it is common knowledge that 1060's can't reach 25 MH on Ethash.
With stock setings it can get up to 23-24MH but power draw is @ 100%tdp, equal to 120w which i think it is not worth the extra electricity cost. but it has stupidly high fan temperatures stock with 84,85 degrees celsius.
