Hey guys. I was overclocking my AMD 6970 and I believe I might of killed it but I'd like an expert confirm it. I guess it's worth noting I have the Rosewill RBR1000-M 1000W PSU.
The first unfortunate mistake I made was using the latest beta drivers and an outdated Asus GPU Tweak software (the newer ones didn't allow voltage adjustment).
At every 10Mhz increment I was using Heaven benchmark to see the performance. Midway in overclocking I decided to switch to MSI Kombustor because it's easier to spot the artifacts (second big mistake). The odd thing was that every time I hit ~82C, my computer would freeze and drivers would crash. I reverted it back to stock clocks and see if the issue would be similar and yes, my drivers would crash the minute it hit 82C. This might have even explained why my BF4 beta would occasionally stop responding while playing as well (although I cannot confirm that is the reason). I had the fan left at automatic speeds but it never passed at 50% speed (I assume 82C, although undesirable for long periods, is still relatively safe) so I don't think it overheated.
Anyway, the stupid me decided to try it again. I put it back at 970Mhz clock and 5700Mhz memory at 1.255V and run Kombustor once again. No surprise, computer completely froze at 82C. I forced restarted it by holding the power down. However, now I get absolutely no image on my screen (monitor doesn't even detect anything plugged in).
I took the card out and put in my old ATI 4870 and I got my image back.
My question is, is my card pretty much guaranteed dead? I assume the drivers make absolutely no difference here if I can't even see the image at bootup. Is there any further diagnostics I can perform?
