I presume gpu vram is faulty clock speed should be 933mhz under full load and memory speed should be 1250mhz however the speeds are
constantly stuck on 500hmz core clock and only 150 mhz memory during a benchmark test also the card is 3gb yet only uses 744mb max under load also while playing most games it black screens or has very poor performance tried reinstalling drivers and got latest window updates can anyone help?

Had it for 2 years now never had a problem it makes like a whining noise fans work okay although as soon as i stress test it the vrm temp goes up to like 75c within a minute of full stress while the normal temp reading is at like 50-60c and bought it from a guy online been working fine last 2 years
