Question about gtx 670 voltages

I have a gtx 670 evga reference
When the card is overclocked (1254mhz), and the power is above 125% (the max power limit you can set in evga precision, and the one i have set to is 122%), sometimes the voltage fluctuates between 1.175, 1.162 and 1.150 (is this bad for the card?), i thinks this is because the core clock is throttled down because of the overpower usage, and sometimes because the temp of the card is over 70ºc. Is there any way to lock the voltage to 1.175v? or maybe to a lower one?. When the card is not overclocked (core speed 1100mhz), the voltage is still 1.175v, it only goes down when the core clock decreases, is there any way to set a lower voltage? (i never touched anything, the card always runned at 1.175v)
Thanks
 
Solution
Your gpu is already undervolting even if just by a small margin due to fluctuations in the voltage it is receiving from the power supply. This is normal and you shouldnt worry about it

There may be some way to lock the voltage more tightly, but that kind of fluctuation is normal. It would a be a bigger issue if it were going above and over volting, but undervolting generally isn't a harm unless it starts causing instability.

How do i undervolt?
