OC settings for different cards

Hello all I’ve just joined mining RVN. And I posted few doubts yesterday and all got cleared. Thanks to this wonderful community. I can’t quite figure out the OC settings for the cards I have. Could you please share your settings if you have the same card? 1 – 2070 super ROG STRIX 2 – 1660 super MSI ventus 3 – 1660 super ASUS TUF (Hynix memory) 4 – 1060 6gb (gigabyte) 5 – 1060 6gb (zotac) 6 – 1070 ti ASUS ROG STRIX

I’m struggling a bit to keep it stable and I think my current hash rate could be bit better. So if any one has any of these cards and have found the perfect OC settings please comment. Thanks in advance for any help. Keep mining 😄
