I've had 3 of those cards in my system.
Of the first 3 one cards smelled burnt as soon as I turned it on. About a month later it stopped working. Got it RMA'ed.
A few weeks after that another card broke down. RMA'ed that too.
Now that I just received the 3rd card RMA I installed it and it smelled burned again from the very start (only when under load though). Furthermore another card that I had received a s replacement also died a few days later. That's 4 cards burnt in less than 3 months.
No overclocking, no cheating with voltages, no alternative bioses. Intensity at 18. Cards run very cool probably at like 40% fan speed. wtf is this?! Until what point will this shop keep sending me new cards?! They must see this happening with gamers as well?
How the card burns out: it's mining along fine. All of a sudden the screen freezes, all inputs stop working. After restart it hangs right before where it's supposed to show the windows desktop (even when no monitor is plugged in to the burnt card). Weird thing is, you can still get it to load windows correctly when using the second bios (using the bios switch next to the crossfire link connector) but as soon as you run a game or start mining it freezes everything up again. This is definitely seems like a hardware problem. Something on their ASIC wired up wrong, bad cooling paste or some other low-quality problem.
Why did they even come out with this new revision? The previous revisions worked really well as far as I'm aware. So dumb...
