Hi everyone
I recently purchased a 780, I haven't used an nvidia card since the 500 series.
I'm using the reference cooler EVGA SC card.
Now my question is, are these cards known for overclocking well without voltage changes, or is the voltage changing without my knowledge?
I followed a guide showing me how to OC a 780 using Precision X
I set my power target to 103%
Temp target to 75 C
GPU clock offset to +100
Now I really figured with a speed of +100 MHz I would atleast need a bit of voltage, but I'm not getting any crashes with that boost.
In Heaven benchmark it stays at the boost-clock without down clocking at a ridiculous speed of 1175 MHz, GPU-Z reporting 1.1620 VDDC constantly.
The power consumption in GPU-Z is about 96% TDP average
Is my voltage being reported correctly? because that seems awfully low for 1175
I read a review here
http://www.anandtech.com/show/6980/nvidia-geforce-gtx-780-overclocking-results
that shows he used 1.2V for 1100
That is why having 1175 constantly at a voltage of 1.1620 seems ridiculous to me unless I won the silicon lottery.
Here's a screenshot of all of this happening

I haven't pushed it further than 100 MHz since I'm afraid Precision X might boosting the voltage without my knowledge and I don't want to fry my card, the guide I watched didn't go into detail on voltage.
I should probably mention that the voltage you see on GPU-Z is stock voltage
