I was messing around with my RX580 to try to squeeze a few more mh out of it today and was running into some issues. With the stock bios and overclock in HiveOS I can get about 28.5 mh/s at about 89w consistently with good stability. After running the bios through the PolarisBiosEditor it was pulling about the same hash rate on a stock OC, but when I started tweaking it became really unstable and was rebooting often. I was able to get about 31 mh/s but not without instability. Does anyone have any experience tuning these cards? Is there a good stable bios that I could flash to get the hash rate up?

Has a Samsung memory chip FYI.
