Gigabyte Radeon HD 7970 Burned Up This Morning

[mx19]

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

Same thing here..

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.

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...

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

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.

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.

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.

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

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.

Yea it could have been the voltage problem. Your VRAMs must be running too hot to control the voltage, hence leading to this.

black smoke and VGA gone away
