Topic: Second 7970 Always Crashes AMD Driver (Read 1590 times)

good idea

Maybe your second card is a dud? I bought 4 retail 7970s recently, and 2 of them have died (they can display, but not stable under load). Slap it in a backup machine and run OCCT:GPU:3D or Furmark on it and see if it crashes.

That's an interesting point to raise, I didn't even think to take closer observation of that. It says the display driver has crashed.

I had a similar issues and after a lot of troubleshooting I decided that one of my cards was bad. RMA'd it with newegg and have had no issues with the new card

Hmm it shouldn't be crashing.  Does it say the display driver has crashed or just the device driver?

What are you talking about man. I straight up said YES I have used the uninstall utility every time. Was my first response not clear enough for you?

They're clocked at 1050 / 1550. And yes, they are the GHz edition

How much are you overclocking?  The display driver crashing could be a result of overclocking too high.  Also, are these the GHz edition?  That is, are they defaulted to 1256mV?

Yea before every try with a different driver I've ran the Uninstall Utility beforehand 

thanks for the input though

My setup is as follows:

Mobo - AsRock Extreme6 z77
CPU - Celeron D
RAM - Kingston 8 Gb DDR3
PSU - Corsair 850W Gold Plus
GPU - 2x XFX 7970 Black Edition DD
SSD - Corsair 128 Gb

- I'm currently using GuiMiner + Catalyst 13.1


Right now I can get one of the cards running fine, but as soon as the second card runs for more than 10 seconds the driver crashes and the second card crashes along with it (first one still mines away fine). I've tried every catalyst package from 12.8 - 13.5 beta. Searching the forums I stumbled upon some posts with somewhat similar issues that had been resolved by deleting 8 files (4 from System32 and 4 from Systemwow64), I believe they were 3 amd files and 1 OpenCl file from each, but even that didn't seem to do any good for me. Changes in clock speeds, intensity, or thread concurrency makes zero difference in the issue. The peculiar part about it is even if I switch the card out with another 7970 I own, the same thing still happens. Every single time I attempt to mine on a second card I get the same exact thing. The miner starts fine and I watch the GPU usage move up in MSI Afterburner. As soon as the card's usage hits 99%, BOOM crash and upon recovery the card is right back at 0%.

If anyone has encountered this and could offer any support it's much appreciated!
