Hello last year I bought a XFX R9 280x Double D from Amazon, a couple days after building my newly built gaming pc an i5 4590, 8GB of Crucial ballistic ram, 750w Corsair power supply, ASRock Fatalty z97 killer mother board, 1TB Segate HDD I started to notice that in games I would start to get graphic artifacts textures stretching, pixels that would flicker etc games were unplayable once they started happening. Then after I would exit the game hoping the graphic artifacts would stop I would go and watch youtube videos, I would get lines in the youtube videos as well as just browsing the internet I would get lines across the browser flickering from time to time. I did some research and found out that the core clock speed and the memory clock speed is to high and people recommend to down clock both the core and memory speeds just a little bit. After doing so it fixed it for about a day and started back up again. I called XFX and soon got a RMA after putting the new GPU in and played around in some games and got more graphic problems the problem seemed like it never stopped. I've went about a week or so without having problems and then it continued some days would be better than others. The pictures below make me confused because during idle or even just at the desktop the memory clock would go from 150 MHz to 1500 the core clock would go from 300 MHz and jump up to 850 MHz randomly without having anything on my desktop or without doing anything other than having MSI afterburner open I put some pictures of the hardware monitors could anyone help me with this I also called XFX for the third time and even without having my Warranty active they are still going to RMA the card sadly I feel like this will not help me or fix the problem because RMAing the card once didn't help they sent me two bad cars so what are your guys idea on what should I do? Thank you
