I've done what this guy mentions..

If you set your undervolt in Afterburner and then bring up X1, it will open with the undervolted settings, then close afterburner. X1 will hold the undervolt and then you can control all 3 fans.

(At least I think that's what it's doing)


Anyways.. I don't use PX1 cause the osd does not work in my games (BF and COD).

Crimtide, may I ask what you reduced your overall core clock before undervolting?  Was it -200?

Yes, I set it to -200 to start.  Went up little by little from there.

Thanks Crimtide.
 
I finally did it in Precision and can indeed confirm it works!  I did the following: -200 MHz core clock and then raised the single 0.875 Volts to 1,905 MHz in the X1 curve tuner.  I didn't even have to go to the VF curve button but did it in the main menu screen as shown below.  I hit apply and save and that was it. 
 
I ran some before and after benchmarks on Unigine Heaven and my voltage never went above 0.875 with the frequency at 1,905 MHz (see screenshot below).  Before it was at 1.081 Volts at 1950 MHz max.  However, my temperatures only marginally improved.  My GPU temps dropped from 66 to 62 C.  My memory temps unfortunately stayed nearly the same only dropping 2 C from 84 to 82 C.  I didn't keep track of the before and after power but I honestly think it stayed the same at 350 Watts.
 
Is the fact that I'm running a hybrid contribute to the marginal temperature differences?  Am I doing it right?

Thanks for the shout! PX1 is the way =] unless you are in love with OSDs that do nothing for you unless you are trying to create a content video or just genuinely curious about that stuff.    As far as errors.. I have never had problems with PX1.. 99% of the time it is user error or simple as an update to PX1 reset the settings.. but it takes 10 seconds to put the undervolt back on.

I'm sure Sajin and I are well past the 'user error' part. I prefer AB because it is stable and does what I need simply and with a more user friendly UI. Using the voltage curve in Precision is awful in my opinion. You cannot select and edit single points without needing to add another step. Whereas with AB you can select and deselect points at will.

What exactly do you mean when you say you can't select and edit single points without adding another step?  You literally just click and drag a single dot.  Unless I am misunderstanding you.

That's right. You can select ONE POINT or multiple points and move it/them. You cannot deselect that point(s) and select another one. You have to apply that change, THEN you can select another point. Surely you've noticed that hassle.

But all you have to do is move one point.  I’ve confirmed it works. 


You don’t have to flatten the curve after that single point.  Provided the voltage/frequency point you modify is the highest point (from a frequency perspective), the card will not exceed that voltage for any frequency at or above that point. 

Which means another step for Precision: dropping the core clock prior to opening up the voltage curve. The point is Precision is ungainly compared to the ease of using Afterburner and Afterburner is more stable. I don't get what the argument is. I've been at this awhile. Several of the guides on this site are cribs from stuff I posted on the old EVGA site. I can't recall the last time I had an issue using Afterburner. Sure, if you need all the RGB bling working and the ability to control all fans individually, some of the time, you of course have that option. I prefer set it and forget it.
