Yeah, that's exactly the problem. No clue why some cards are like that when it's obvious that it isn't to do with the quality of the chip. I can do 1150mhz without any overvoltage, so obviously my chip isn't bad. Yet I'm capped at 1187mv. And then there are other cards capped even lower, like with no overvoltage at all. Makes no sense.

The custom BIOs overwrite GPU Boost 2.0.. which is irrelevant. I can flash custom BIOs right now and run 1.5v through my chip.

So it is the GPU Boost 2.0 aspect of the bios which is limiting the voltage on each card, do you think?

I think so, but what causes the bios to "know" that the voltage should be limited- does it detect poorer silicon and adjust accordingly? If the card is capable of steady 1.2mv w/ modded bios, why the throttle by the stock bios? Why indeed....

If your card for example only gets to 1.161mv and never runs at the advertised "boost" clock then there is reason for concern. If your gpu clocks at say at 1150 mhz while only using 1.187mv, as mine does, it runs as advertised and then some, and actually needs less power to do it. Which is a win in my opinion. I was bothered by this before but am well over it. If it bothers you that much just do some research and at your own risk run a modded bios that eliminates GPU boost entirely. End thread. If you do your homework first it is easy as pie and you won't brick anything. I will say it was refreshing when I tried it briefly before to be rid of all the "offset" and "boost" nonsense and back to classic overclocking.

I still wish someone would post their BIOS dump of a reference 780 that can do 1200mv so we can put this whole thing to rest =/

Just want to say this thread has been a very interesting read since I myself own X2 EVGA GTX780 Superclocked ACX cards and I appreciate any information that is posted about hardware I own regardless of relevance. I myself have an ASCI score off 63% and 64.3% but have no problem getting 1.2v. The max overclock I can get on the core is +50 @ 1150Mhz (+38v) but I'm happy with this since my ram can get +350Mhz and so does make up for it.

Got my ACX 780 today and couldn't be happier! Things are looking good so far and she boosts over 1100 out of the box and will allow 1200mv just fine. Who wants my BIOS?

Really guys?

Let it go... Much like people who 'bench' cards. It's quite simple.

If this cards doesn't do what you want it to, sell it and buy another one. This close to release date you won't lose all that much money. On the next card you may very well get one that does what you want.

As far as RMA is concerned...
You want EVGA to take back a card that performs exactly as specified (Note: EVGA does not guarantee voltages) for clock speed, memory speed and would benchmark close to identically to every other card at stock?

I understand your disappointment, truly I do. However, this is not the right way to go about fixing it. Simply buy another card, sell this one and accept your losses. No-one is going to guarantee anything past being able to achieve what's printed on the box.

I'm buying some cards from EVGA when the Classified HC's come out and I hope they perform well, but if they don't. I'll simply order another one and put the 'under performer' on the FS section.

No need to go to such extremes for such a small issue, there will be many people out there who have no issues running a card at stock, you won't have any issues selling the card on.
