Is it possible to damage a graphics card just by increasing its boost clock?

I recently bought an Asus Strix 980 Ti and I wanted to overclock it. So I used GPU Tweak II as the tool to do this. I did some research on overclocking and read that the first thing you're supposed to do is raise the power target, and then raise the clock speed until you see a crash on a graphic benchmark or something, that way you kind of get an idea of what you have to work with.

So, I did just that. I raised the power target to 110% (this is the highest I was allowed to) and then I raised the boost clock little by little. I never actually got to the point of anything crashing, but I did see an artifact or two. After I raised the boost clock by about 310 MHz, the FPS of the benchmark actually went to about half of what it was before I did any overclocking! I put the clock and power target back to factory settings, and the FPS was still about half its original amount. I restarted the programs, rebooted the computer, and still FPS were low.

The next day, things were back to normal. But now I have the question: does raising the clock too high damage the card, even though temps stayed below 73 degrees C the whole time?
Thanks for any help I might get.
 
well if it stays under 73 degrees C it won't be damaged and if you set your clock speed to high it will just crash (also known as bluescreen) but if you set your voltage TO high your temps can rise very very quick and also can get very very quick above 80 degrees C and with some bad luck your GPU get damaged and in this scenario it will be dead or unharmed i don't believe there is something between nothing and dead with the CPU GPU and Mobo. However the RAM PSU HDD SSD and SATA cables can be something between nothing and dead.
ps. it is possible to damage your mobo with to high voltages but that chance is really really small
 


So what do you think caused the temporary reduction in performance I told about?
 


it could be that your driver had a bug/glitch but i don't think it will happen more often
 


I think you might be right. It's been doing that sometimes since then and I get a message once in a while saying that the driver had stopped responding and had recovered. I'm not really sure what to do to fix this. I guess I'll just reinstall the driver?
 
Wait... You shouldn't raise the voltage for the GPU. Since you're raising the boost clock, the stock voltage is needed to maintain stability at the stock speed. It's boost speed you're raising; boost speed is needed when you're running something intensive and the GPU needs to keep up.

And as for overclocking boost clock, I don't see a big issue with that. Stress test and see if the boost clock is stable, however.
