i have club 3d 7850 card royal king version and i am facing a issue since i bought it. The issue is that when i ran my card on default clocks then during playing game lines appear on the whole screen like pink or silver or black and the pc hangs until i restart it and when i overclock the card the lines appear sometimes not in most cases. And also when i use msi or asus gpu tweek and break the overclocking limit of 1050 the card dont function at all but people are overclocking it at 1200mhz . what is the issue with it?? is it defective??
All the drivers are up to date..
