Does anyone know why Gigabyte Aorus or MSI RX580s are using almost 180W per card once mining ETH at 1425 clock and 2175 mem with flashed BIOS just copying 1750 timing values to 2000. If I use stock clocks the cards still eat around 160W, where this video shows the same exact cards and timings get 110W per card. I am getting the right 29-30MH/s rate but this power consumption is insane. Please advise.
