Video card has some sort of vdroop ?

post #1 of 3
Thread Starter 
For example, if the GPU usage is 99% the voltage drops to 1.205V and when the gpu usage drops from 99% the voltage is 1.22V

Look at these pics, runned unigine heaven benchmark, as you see on the entire test the volts are 1.205, and one seond (when i exit unigine program) the voltage is 1.229V

Why ?

The same happens to my first 780 Lightning.
Might be your temperatures going to high and card sets voltage lower. Think the limit is around 80c or so.

Although it happens to me even though temps are ok.

Links don't work for me though, so can't see them.

I think postimage is down...

Well temps are within 70 degrees, basically in games with 99% usage it drops to 1.205V and for a fraction of a second when i exit games or stress programs it displays 1.229V
