Yea it could have been the voltage problem. Your VRAMs must be running too hot to control the voltage, hence leading to this. 
I received a notice from USPS that Gigabyte has sent me a package. Hmm? They said they were sending a check because there were not anymore 7970's in stock. If they are sending me a card I hope it hashes at least as well as the 7970.
I will update when package arrives.
Regards.

Update:
The package they sent to me was an envelope with a usps tracking number on it containing the reimbursement check.

Simply RMA this card and install a new one, received from Gigabyte!
I lost one about a month ago. Sent it in for RMA. They could not repair. They said they would send me a check if I sent an invoice.
I hope to get a check this week. Have two survivors left in the rig, mining litecoin. Anyone know if the r9 series play well with the 7970's?
I sent RMA request for my dead 7970 yesterday.. I hope they fix or replace it for the same card.
R9 and 7970 should play well together, but you need to a) Update drivers and b) Edit scrypt bat file to change mining settings to add a new R9 card

In the last image I can see balls of melted solder.
This is an indication the temperature reached 180 and 190 °C (360 and 370 °F) at some point.
The thing being on fire is a temperature issue! Get a thermometer gun.

this is why i have a temp gun and run them slower than most and stable. hardly any hw errors and a few rejects. a 100mh/s gain on each card isnt worth it imo, because if one goes out and you have an empty slot for a week or 2 you prolly take more than what that gain has given you.
The fan directly above the vrm heatsink may be the culprit.
When I turn the fans by hand, there is significant resistance in that one bearing.
Also tried hooking them up to a psu, and the one over the vrm's did spin at a much lower rpm.
If i stopped it with a finger while running, it would only sometimes start by itself.

Same thing here.. Card was undervolted and running 76C core temp.

75C- 77C. Open crate rig. I don't think it was a temperature issue.

Great... another case here. 
It seems to be happened to Gigabyte card more often than other. I guess I will just sell off mine ASAP. Worried about it a month ago when found out a lot of similar cases. Now I am just worrying it more. It does not worth the whole damn house being burned to crisp just for a damn faulty card. lol...

Guess I will steer clear the Gigabytes in the future.
Card was undervolted and running 76C core temp.
It has been mining for a year, and on a powered riser.

Hi did you ever find out what caused this? I had exactly the same happen last night on the same card. I have 4 of these, is there any way i can stop this happening on the others?
Thanks
Max
Thanks

I run that card mining ltc 1045/1500, stock volts, ~65c for 2 months @~650khash
Runs alot cooler and faster than the XFX DD I had. No problems... Yet!

Ah ok. Your first pic is a lil dim, and not a good angle. You wanna take the heatsink off, and take a better pic? Yes, you can usually take the heatsink off and repaste it without voiding your warranty.
My curiosity was outweighed by my desire for a refund so the card is already on its way.
This mystery will have to be like Sasquatch or Nessie.
Moved the card to an empty machine. Set it up. Turned it on. Flames and smoke and crackles!
What a way to start the morning.

you mining litecoin or bitcoin ? Have card like that in one of my miners, and scared it is going to catch fire too ! have not seen gpu burn like that before.

That looks like one of your VRMs blew up. That's not the actual GPU core, but actually farther towards the end of the board, correct?
That doesn't really surprise me. These Gigabyte cards are known for running the VRMs really hot, as there's only a TINY little heatsink on the VRMs, and the air that cools that tiny little heatsink has already passed through the main heatsink and warmed up a bit. I had to struggle with my Gigabyte 7970 to keep the VRM temps below 100C, and this included undervolting, high fan speeds, stick on heatsinks on the back, and a fan blowing on those extra heatsinks.

The area of the burn is to the right of the silver heat sink (I think that is where the voltage regulators are). I vote for a fluke component failure or a short circuit involving the heat sink.
In any case, it was neat and I am glad I was there when it happened.

(not my exact card but layout is the same)
After putting new thermal paste on my GPU, VRMs, and VRAM, and cleaning the dust out of my heatsink, my temps are now 75C on the core and 86C on VRM1, when overclocked to 1150 MHz at 1.25 V on the core and 1750 MHz at 1.6 V (default voltage) on the memory. Before, they were 85C on the core and 91C on VRM1, when overclocked to 1125 MHz at 1.2 V on the core and 1750 MHz at 1.6 V (default voltage) on the memory. VRM2 remains a nonissue. Ambient temperature is 25C. This is a reference 7970 using the stock cooler, and the fan is at full blast.
In the future, always replace the thermal paste on your GPU, VRMs, and VRAM, and make sure your heatsink is dust-free. It'll keep your temps down.
