Hi, so I wanted to try out how much my computer can overclock with a program called Evga Precision X 16.. So my graphics card is GTX 960 WindForce 4 GB.. I tried overclocking it on a game 7 days to die with full graphics possible.. It actually ran very well in start around 40-60 fps but as I reached around 1533 MHz and so was the temp raising reached only 60 C and played with that much for few mins, my screen blacked out for a second and it turned all of my overclocking stats back to 1444 MHz (or around that, I don't remember well, just to basic boost of graphics card) I have tried increasing my memory clock too, it was around 3545 MHz when I was overclocking it.. And I have question for this too what does memory clock really do and does it need to be overclocked ? And my second question is why did it black out and put all my overclock settings back ? (my solutions that it reached its maximum power which if I'm not wrong is set to a 100% max out of 150%, and second solution, something was corrupted and failed to continue doing its work..)

If you go read your Windows Event Log, you may find a message saying that the graphics driver crashed or that there was a problem detected in the GPU. If you see either one, the reason why your settings got reset is because the GPU or drivers detected an error and the drivers reset the overclock to safe default values to reduce the likelihood of more errors causing the system to crash. In that case, 1533MHz core or 3545MHz GDDR5 may have been too much.
Why overclock the RAM? Because graphics rendering is memory bandwidth intensive. Overclocking the core does you no good if the core is already waiting on VRAM most of the time.

Stopped responding is just a different type of crash: instead of executing an illegal instruction causing it to get terminated, it simply locked up. Either way, it still means that there was an internal driver or hardware error to cause the driver to end up in a dead state.

It means that you probably pushed the OC too high for the power limits you set. Unless you did something potentially reckless like bumping the core voltage by 200mV, the likelihood of permanent damage is very low. Reduce the overclocks by 10MHz and see if you get another driver/GPU crash. Rinse and repeat until you get no more crashes, then back off by one last 5-10MHz as a safety buffer to account for future wear and give yourself a little margin - you don't want your GPU to crash just because it got 1-2C warmer than it did during your OC testing.
