I've got Gigabyte RX570 cards, with Samsung memory.  Trying to mod isn't working.
Once I change the Strap values the card is no long recognized by the sytem, even though it was working
fine beforehand.  Blockchain drivers are installed and working, is there anything else I need to do?

Tried modding the card myself and also modding using https://anorak.tech/t/gigabyte-rx-570-aorus/34867 mods.
Neither worked.

Currently mining Monero at 770 H/s and trying to get up to 900.

TIA
