I feel this warrants a thread. As many of us like myself have paid nearly 3k for parts, only to find out that what we purchased is no different than an ACX.
 
I have experience with Classifieds, as I own a 780 Classy that overvolts just fine with the tool and with EVbot.
 
However, the 780 Ti Classifieds that I purchased. ALL 3 of them, crash when overvolted at all, with either EVBot or the Software OV tool.
 
The ONLY way it remains stable is to treat it as you would an ACX, and ONLY use Precision to overvolt up to the 1.212v limit. This is NOT what most of us purchased the card for. Many of us already have waterblocks on the way.
 
I have tried other BIOS', only to be let down.
 
This seems to either be a Precision issue, or something that EVGA can perhaps fix with a BIOS update.
 
Either way, it does NOT work in its current form.
 
 
 
I am not the only person that is having this issue. My friends over at OCN are having this issue as well.
 
Not ONE of us has been able to overvolt past 1.212v and not BSOD, even when running at stock clocks.
 
I sincerely hope this is fixed, or can be fixed for that matter. I really would rather not return my cards, or downgrade to 780 Classifieds just to retain the tweaking features that I know and love.

The problem is with EVGA Precision. I just tested it with Afterburner and was able to overvolt until I hit the max of 95C using Skyn3t's BIOS. I'm on air until Monday, so I can't do any more than that, but I got up to around 1.33v and up to 151% TDP on skyn3t's BIOS, but hit 95C in Firestrike windowed mode, and had to stop.
 
That's good news I guess. EVGA just needs to fix Precision, and we should be ok.

Thats not good. My cards arrive on Monday. Maybe I will keep them in the box for return if this is a larger issue. Hopefully we can get some info soon. 

Looks like I'll be doing the same as mine also arrive on Monday. Hopefully Jacob can chime in here.

Well if it doesn't work with EVBOT then it isn't just Precision that needs to be fixed.

I have the same issue with my 780 ti classy. Enabling k-Boost is automatic crash. I also have trouble keeping my volts and clock speeds from jumping up and down when stress testing.

What BSOD Code are your seeing, like 116, 101, 124?
What is your Hardware, Make Model and so on?
What are your Bios Settings like vCore and so on as well.

You would have thought they tested these cards before shipping. Maybe a new BIOS can fix 'em. The cards are pointless if they are stuck at vanilla voltage. 

I just called for a RMA but since I posted this morning the problem has gotten worse. Stress testing with precision x I can't get it to go past the "boost clock" of 1085 MHz. Where as when I first got it the card would automatically go to 1150mhz at 1.2v by itself.

I did just RMA it. And it wasn't because I couldn't overclock the card. It was because the card failed to perform to the "boost clock"of 1085.

This card is confusing. I just did a run of 3dmark11 and it ran fine when I ran everything stock. But it doesn't like the stress test from evga... I guess I'll have to start messing overclock with a different stress test program.

^^^ How high are you guys trying to OC these Cards...just curious??
My 780Ti SC reference Cards reach +155 Core n +300 Memory with just the available +75mv & 106% Power Target ......for 24/7 gaming I run +120 Core / +200 Memory and NO added voltage......boosts to 1228....odd, I'd think these Cards would get you to a Boost of 1300 Mhz without too much trouble.

We have found the root cause and this will be fixed via official update this week (hopefully Tomorrow)

Jacob- will this be a firmware update? Please post a link when update is ready. Ty

Working on the weekend. Thanks Jacob.

 I asked about an update on this the other day...  Hopefully the firmware comes out soon....
