At first I used polaris bios editor and copied 1500 straps to the above ones, then i used the one click timing as suggested in a post above.
Does it matter which bios i flash on the cards? i notice some of them have the switch in the other direction, all show as same bios in dashboard

Should also mention that i backup bios from one card and then used the modified version of that on all the cards, is that bad?
