I would be interested in whether the CTD’s are actually just a driver or software problem? I use an RX 6800 xt and this achieves a maximum of 260 watts under full power. I didn’t overclock it. However, I only have a 650 watt power supply. However, AMD recommends a 750 watt power supply. What kind of power supplies do you have?
