Risks of overvolting?

[SlaughterSmurf]

So I have an EVGA 780 ti SC with the ACX cooler and I appear to have lost the silicon lottery, I get crashing and artifact if I push it above 1200 mhz boost (+40 mhz) and that makes me sad. I was thinking about adding some voltage to the GPU via EVGA Precision. What are the odds of adding voltage within the limits set by EVGA precision and bios will damage my card? Is it safe? The limits are set to +75 mV, is that a lot? Right now my temperatures are fairly low peaking at about 72 while running Furmark in my GPUs OC state so I don't think thermals are a huge issue. Is it worth the risk to possibly get a better overclock?

Well this is disappointing...

[Doughnutnator]

Well, it will run hotter and take more power. I would say 60mV is a safe spot.

The risks: Reduced lifespan of the GPU, unstability, more power draw, more heat output...

I wouldn't recommend overvolting more than 50mv without watercooling, it puts lots of stress on VRM's, and sometimes VRM's can be hotter than the GPU itself, while VRM's are rated to run extremely hot, that doesn't necessarily make it a good idea.

How would I check VRM temps? It doesn't say in EVGA Precision and I can't seem to find it in GPU-Z

The standard 780 ti's / 780's don't have a temp sensor there I don't think.  My 780 acx's didn't.

lol wtf why

because it's not a built in feature? i dont know, do I look like an evga rep? >.>

Well it was a rhetorical question, it was more of a "WTF that's dumb" sort of thing.

Probably because they aren't meant to be overclocked much more than their stock voltages, there is cards specifically designed for those types of things that have VRM temp sensors.
