My 780 also only goes to 1.187 even with K-boost enabled. On my "old" Titan enabling K-boost worked but not so with my 780. Highly doubt you have a bad card. Running a custom bios will get that voltage up to 1.2, google search for Svl7 bios and you'll see people are getting great results (sorry don't want to get in trouble for posting any links) but we shouldn't have to resort to that. I've never run a custom bios before and am reading a whole lot before I try it, might attempt it this weekend if I do I'll report.

I hit 1.2v with +38. Have a stock BIOS 780 Vanilla.
 
That is unless you are talking about something else. This is what Precision looks like:
 

Odd, do you own a blower or the ACX?

Whats your GPUz look like?

Nothing different from mine @ stock. Guess an EVGA rep will have to shed some light on this.

Yup, standard Titan looking cooler on the vanilla GTX 780 (03G-P4-2781-KR).

Wow. Really mind blown right now. I understand that some cards will overclock with stability better than others, but this is a whole different level of making me feel like I got shafted. I just don't know what to say right now.
 
What in the world would make them look at this card and say "let's lock the voltage at a lower VID than on other cards"?

I use Afterburner and not Precision X if you want to try that. But like I said, this isn't an unusual situation. Your card is only guaranteed to run stock clocks/volts.

72.8%
 
Load the card with Valley or Heaven and see what the voltage does.

Apparently it's 72.0%. What's yours?

 
Did I get lucky? SC edition here, I have 77.4% In all honesty, I have barely touched OC'ing this baby.
 
But yeah, same thing here. have not seen my voltage go past 1.187, even with +38...
 
EDIT: In all honesty, I don't care much due to the fact how much of a BEAST this card is stock, but would be interesting to figure out the cause.

+38mv applied and still only 1187mv while running Unigine Valley.

Yeah, I don't know what the story is here but I'm kinda heated. Oh and just to add to the mix, I bought 2 GTX 780's at launch, and my other card which I gave to my wife, is only 65.8% ASIC. Have to figure out whether or not her card runs at 1200mv or lower than 1187...

Yep, her card also runs at 1187mv max voltage. And that's with a 65.8% ASIC vs 72.0% so I doubt it's that. Really frustrating. Like I said I can cope with the reality that a card has hard limits on what it can and cannot handle and that this will vary from card to card. What bothers me is when, for no apparent reason, my card was forced at a hardware level to have artificially lower limitations vs other cards that fall under the same SKU. That's nonsense. I hope someone from EVGA can step in and explain what's going on here and why some cards would have this arbitrary cap.

 
Hello, not sure what your particular issue is, but I do want you to know that it isn't a malicious practice to sell substandard cards.
 
Manufacturing processes are measured in microns, anything mass produced will inevitably have great units and terrible units produced from the same assembly line. The width of pipes varies minutely on every piece of electronic hardware any of us has ever purchased. However, as monitoring tools on high end electronics get better our ability to distinguish these differences gets better as well.
 
An example, SC cards wouldn't exist without manufacturing process differences. They are the same cards from the same line from the same machine, some just test better than others due to microscopic differences, and thus are sold at a premium. That keeps us from being totally at the mercy of the "lottery" as it were.
 
Same thing in AV, as when you purchase a set you take part in the panel lottery. Will you have excessive clouding? Who knows. Actually, Samsung would do well to sell a SC set with a guarantee of minimal anomalies or dead pixles.
 
Anyway, point being, the only reason we have to overclock these cards is because of these manufacturing differences. Machines can only guarantee a certain minimum quality range on every dye on any circuit board, so they have to plan around that minimum and give us "base clocks." If we're average or lucky, we should be able to increase those base clocks(overclock) and increase the speed of our hardware to personalize it to our lottery luck.
 
So, tl;dr its not malicious, its unlucky. :(

Both of my 780's show 1200 running heaven.  Not sure what the problem is.

As I said already, and I will repeat.

If you take a look at all those people with 1200, you will find out that they all overclocked their CORE CLOCK.

I say that he need to overclock his core clock so over voltage take effect.

QUESTION: How can I check my GPU's ASIC quality ?

Yes, Iroveth, how exactly do you do this, is it in precision?
 
PS I am trying to OC just by adjusting my clock offset, on my 580 with older precision you could adjust the base clock but I just got the new precision(it is a little different) so maybe the OP is like me?
 
Also with just offset, I can't get "test" in precision go over 1100, but when I enabled KBoost I got to 1200. Has OP tried enabling KBoost?

For me, I tested with my GPU Offset to +100, and Memory to +140, and in voltage I did +38. card will still not go above 1187mv. If it matters, I have the 780 SC, reference cooler.

Iorveth

Okay then I was wrong :)
It's just all the people  with 1200 have their core clocks overclocked XD

 
I don't, neither does a bunch of other users. That's not the problem here. The problem is, and it goes back to Titan, is that some cards inexplicably are capped at a lower max voltage. The only way to circumvent this is to flash an aftermarket BIOS, which I am not keen on doing.
 
I've accepted that 1187mv is my limitation and will just look for whatever my cards max overclock is. I need this card to last me approx 4-5 years so I will prefer a lower max overclock if it means longevity. I just wish I had a concrete explanation, particularly from the manufacturers, as to why some cards get lower max voltage capability. It just doesn't make sense.
