My experience

Sapphire Radeon 570 Nitro+ 8GB Micron
These cards are awesome. With polaris bios editor one time click patch + OC and undervolt I get 30.9 hashrate on eth.
1150/850 2150/850 powerlimit 70%. 13gpu + mb etc. draw 1525W from the wall.
0 errors

Sapphire Radeon 570 Nitro+ 8GB Hynix
Good enough. One time click patch + oc and undervolt. I get about 28.x and 29.x hashrate on eth.
I dont remember oc and undervolt settings, but I think it was 1200/900 2100/850.

Sapphire Radeon 570 Nitro+ 8GB Samsung Micron
I hate these cards. Used one time click patch (ubermix 3.1 for samsung and GOOD for micron). I get about 27.5-28.9 hashrate on eth.
1175/975 1975/850, powerlimit 70%. Some cards show 0 errors, some 625 error and one card 23000 errors after 3 hours mining. They are so sensitive! They use a little bit more power than micron and at the same time they have less hashrate.

Sapphire Radeon 570 Nitro+ 8GB Micron Samsung
I havent tested this card yet. What is the difference between Micron Samsung and Samsung Micron?

Request: Anyone have the original bios of radeon 570 Micron Samsung? (Not Samsung Micron) I think I f**** up this bios. Forgot to take backup.

Whenever I test new settings that is working I will update this post. Please keep this thread nice without ten thousands of posts (update your post when new settings are successful).

I get 32mH/s with hynix, Undervolted to 800 memory 2250. quite happy about them.
