    290 downclocking to 300MHz when it reaches 90C


      Hey all, when stressing the GPU the core clock is stable, until the core temperature hits 90C, than the core clock will jump to 300MHz (P0?) and immediately go back up to the normal speed. This is really annoying because it causes stutters when in-game.
