Gentlemen it is with great pleasure to inform you that I finally managed to get my Zotac Solid 5070Ti OC to 3.2ghz stable after one month of tweaking.
The solution was just to move core clock slider to the right and don't touch the curve.
Tested in Black Myth Wukong, Silent Hill 2, Dragon age Viel Guard, Cyberpunk.
The most important was Black Myth Wukong as mostly the crashes happened in that game.
Temps are between 57-64° with power consumption around 295-315w.
