hi, after used your free polaris 1 click my 570 8gb only from 24.5mh increase to 25.5mh without OC, both of the card are same Samsung chip and Biostar brand. so is that gpu problem? so the new version of polaris problem? Im using window os phoenix miner 5.4c. Using AMD Radeon Adrenalin Edition 18.6.1, not going to use the newest driver because it will pop out wattman settings have been restored  bla bla bla.


btw i am using biostar brand, if i want to buy 570 8gb Performance timings from your shop, which should i go for?
