Can OCing GPU too much cause death?

my card is factory overvolted...
EVGA FTW edition cards are clocked and volted higher by default to my understanding.

Temps probably killed something...

was 98c core temp? What about ram and VRM temps. Maybe one of those had a temp spike that killed it.

I did fold on the cards for extended periods of time.

Maybe that was my problem lol...

this time try applying a better TIM to the card in addition to keeping the fan at 100% if you plan on doing intensive overclocking and folding

you could probably flash the bios to get some better clocks out of it if you would like higher clocks

folding at 98 degrees will probably kill your card, and think about it that temp sensor probably isn't internal right in the core

You guys freakin fail at reading.

So your asking if there is any potential damage, now that they are under water?

I've had good luck with both my cards and they are both under water. I took the shaders over 1900mhz on my 275 to see where the straps are and only stopped because it was getting artifacts at idle. It runs pretty high clocks, while folding 24/7 and I've yet to experience and sort of degradation. My 260 has been folding a lot longer than my 275, at high clocks with increased voltage and is still going strong and continues to fold at the same clocks as before. Both of my cards barely go over 40°c.

I don't think that there is a point where you risk damaging the card. I think that it will either crash or something else, but it shouldn't damage the card. I've had countless crashes and blue screens do to pushing the clocks and it works just as it did.
