Ok I had problems with my older card and sapphire sent me an upgrade, the R9 380. When I installed the new drivers the wattman interface looked different from what it was under my R7 370 card. Can someone who might have this card suggest the settings on the wattman? I was told with the old card to set the power limit to 20, would that be the same for this? This is my setting for now, is it ok, too much, or not enough? Thanks.
