Hi guys i just got a rig put together with 7 rx 480 8GB cards and im trying to tweak the power settings to try and get what im seeing elsewhere online (the best being aroun 70W per card) instead im getting twice that at roughly 146w per card. ive tried enabling extreme undervolting and following what other posts have said and i just cant get it to come down any lower than that.
Ive noticed this with my other AMD system too. One has 4 rx 5600xts eating around 160w and wont come lower to what it should (80ish) and my rx 5500xt is just as bad, eating around twice what it should. All of my AMD cards seem to eat crap tons of power. but my nvidea based system with two 1660 supers seem to go within their power limits just fine.
