so first thing, I used MSI Afterburner
when MSI Afterburner is open use CTRL+F and it will open the Voltage/Frequency curve editor
so the Zotac is using 0.812V on 1733MHz Core Clock speed. you need to put the whole line on the same height otherwise the card is going to jump up to higher volts:
the memory clock doesn’t matter much, and the power limit is on 65% and temp limit 67%:
the Gainward is using 0.825V on 1770MHz Core Clock speed. of course you need to play a bit around as not every chip is behaving the same:
same limits like on the Zotac:
