download msi afterburner or evga precission x software, instlall it, open it up and start adjusting gpu core clock by say 10mhz steps, after every time run one loop of valley benchmark, if you observe no artifacts and it doesnt crash then you can add another 10 and so on untill you crash or see artifacts, if you crash then you can try increasing core voltage a bit if it , should help but not always
