Dear AMD. 6 months ago i bought "Sapphire Radeon X 480 4gb OC edition". This graphic card is perfect. I love it. But last night, something happen to graphic card after i installed "Sapphire Trixx softwere". And i want to ask you something. In this softwere, there was a value like "+11724mV" in GPU Voltage section. And i hit apply button. But it was a mistake. After this mistake, my screen turned off but monitors power led still working. Than i restarded pc and unistalled "Trixx". Now, my pc works normally. My question is, what is this "+11724mV" meaning. Is there a something wrong with my graphic card? Is my graphic card or mother board get damage? Or this "+11724mV" value only a visual bug? In this case, i need some advices. Please turn me back. Thank You.
