Opened original ROM of Sapphire Nitro RX 470 8GB to copy timings from 1750 to above and found strange values of timings.
http://imgur.com/a/qpd8uDoes anyone have any suggestions on how to edit this kind of ROM to increase hashrate? I tried to flash this GPU with modified roms from another sources but it bricked every time.
You are using a version of Polaris Bios Editor that does not handle ROMs with multiple sets of straps.. This one should do it
