I picked up OEM cards from a friend, idk how he got them. Those warranties DO go through amd. The warrenties on my OTHER cards were properly registered. After I sent the card in, I got it back every single time with different excuses. I have tested my components on different platforms as they are all brand new. I have never had good luck with amd, and I think the factory OCing of the cards is what killed them (I know it shouldn't, but I know my PSU isn't the problem because I have switched and the issue persists.)
