More voltage, low heat and crashes

[Guest2]

When I apply more volts and increased power limit to my 980Ti the card will still crash when applying an overclock even though the card is only at just over 60c (using 100% fan)

Does this therefore mean that with the same voltage and power limits and water / LN2 cooling that it would still crash? I am only presume that the voltage is still too low for the overclock but then I have tried 1.3v overboost with 100% fan and it still crashes as a low temperature.

If this is the case, would an extreme cooling setup only work with specific cards?

Maybe it's not the GPU that's the problem? What else heats up as you increase voltages? VRM's?

What card is it and what overclock are you applying? Obviously each chip will have its limit in terms of the speed it will run at and once you've reached this throwing more volts at it is only going to increase temperatures and decrease its lifespan. Out of interest what is the card's ASIC as I believe this can give an indication of the power / cooling requirements for overclocking.

EVGA GTX 980 Ti Classified
ASIC quality - 70.7%
This is when untouching the memory clock but setting quite a high overclock - 1520mhz. Voltage of VRMs is (i believe) un-changed and stays at 1.20v.

Overvoltage max reports 1.212v, DMM reading 1.236v
Overboost setting 1.250v, DMM reading is 1.271v

It seems pretty happy at 1470core/4000memory at the moment so will leave it at that. Maybe it needs to be under a certain temperature like 50c for it to hold the higher voltages
