GTX 780 Ti Ghz (GV-N78TGHZ-3GD) Unstable, crashing, and freezing

[ExGreyFox]

Hello GIGABYTE

There are tons of reviews and forums all over the internet of people having the same issue with this card and also the OC version. Its unstable, causes crashes. I currently own 2 of these and I know that one of the cards for a fact is rock solid and works very well and is stable. However the second I bought is very unstable and causes all of the symptoms that almost every person is having with this graphics card.  Is GIGABYTE aware of the instability of this product and is there anything being done to remedy it? There a tons of reviews of these cards all over the net with the exact same issue. In my case, I did everything from wiping windows 7 and re-installing a clean copy to flashing my motherboard BIOS to latest version, re-installing different versions of the nvidia drivers and nothing worked.

Here is a good forum post on this exact same problem from someone else:

I am 100% certain that this has to do with a bad batch of cards from GIGABYTE. Would be nice if we can get an official word from GIGABYTE on this, no shame here guys, just admit it if you made a blunder so that we are all on the same page and know for a fact that its your product that's faulty so that we're not all sitting here pulling our hair out thinking its our PC's that's the problem when its not and running the risk of trying risky things and actually damaging a well stable and working PC over a product that you sold us faulty out of the box.

Hello,

I also have purchased one of Gigabyte's 780 Ti Windforce 3x cards (GV-N78TOC-3GD) and am experiencing the same issues as the OP in this forum. Scavenging the internet I can see that the problem does not seem to be a few a series of flukes but rather quite an endemic one. I have heard something on the order of 4 out of 5 faulty cards and retailers receiving countless RMA's of Gigabyte's 780 Ti's. 

I would like to see Gigabyte to take this faulty series off the market so that others would not have to go through the tedious and pointless exercise of returning items.

GIGABYTE will never admit they made an error with these. Best to just not waste your time and go with EVGA. I got 2 replacements for my faulty GIGAs***E card and both had the same problem. No excuses GIGABYTE. You are selling us $730 dollar paperweights.

Hi, sorry but I have bad news for you.

A LOT of the Gigabyte 780TI GHz have this problem. There are several threads around the web:

...

The real bad thing is that Gigabyte just won't admit that there is a problem (most of the time RMA is not accepted). I also had a pointless discussion with the Gigabyte support.

The only solution is that you modify the BIOS youself (you are losing the warranty!) as described in the links above. If you have the possibility change your card with an other brand (EVGA or whatever) - it seems that they are working as promised.

have a nice day

Do they actually pay attention to these forums?

I'm also having the same issues, only got the card last week. Already been refused RMA at Overclockers UK which has coat me an extra £11 in postage and packaging.
