Hi,
  After tired of looking for solutions since last 2 1/2 months, I am requesting support from community.

I brought 10 Zotac GTX 1060 3 GB mini's in June 2017.

Out of 10, 3 had Samsung memory and are doing great with 18 MH/s on stock and over 23 at +100/+850 with claymore 9.8.

The remaining 7 cards are Hynix and are performing poorly at around 14 MH/s and would crash upon attempts to overclock.

Could there be a possibility of getting better performance out of Hynix memory cards as well?
