You're pretty much fucked. Almost no 5970 are under warranty anymore, and if you manage to get one to send in, you'll likely get a 7970 back. Either mine the card into the ground at whatever settings you can get it stable at or resell on ebay and pass it on to the next poor sap.
Haha, a 7970 would be a blessing! Anyone knows how many years of warranty do xfx offer on their GPUs?
I think at this point, that GPU mining is still profitable but is not going to last too long, maybe cheeky-selling it would be best
Think you should try to set 0.95v and 600Mhz core and check how it will work, if it will be stable - set 610Mhz, 620Mhz, etc. before it will crash. Perhaps the result would be a good. Also, how much you paid for it?
I have tried that and it will not do anything at 0.95. Nada. Has to be 1 or 1.0375 to bring it to life. Also it doesn't like low memory clocks :S
At the moment is happy with 1.05/800/600 but the fan sounds like a rocket to keep it at 70ºC. (Sisters are mining at either 0.95/680/180 or 1/780/180).
I paid £200 for the thing! That's why I'm so pissed off.
Sounds like the exact same problem I had on a 5850 with a burnt out cap...
It would boot in to windows fine but die after trying to mine with the card.... sometimes it would mine for hours.... sometimes seconds...
Andrew, I had that with an Asus 5870 v2 (which I managed to RMA) but it was never artifacting. Just dying/hard reset/100%fan. This is slightly different. Could be electromigration? ¿? (he, he making use of the spanish "¿" makes it even more confusing)
Thank you guys by the way for answering
