I have a problem with my rig, with a 5870 graphic card,
this card had this problem since i bought it, but I never cared because I never needed to restart the rig often.
Now I'm away from home and a crash of the rig can cause me hours to restart it.
This card (Sapphire 5870) make the driver to crash,
everytime I open a miner I receive this error "display driver stopped responding and has recovered"
and the miner remain stopped (shows 0MH/s)
To make this card to mine I need to start the miner a few times (usually around 6-7)
make the driver crash all those times and one time is the lucky one, when the card starts to mine!
After the card starts to mine it will be mining forever without any problems...until next reboot.
I tried differents over/underclocks but nothing.
I have latest drivers (with the previous instead of showing this error it showed BSOD)
With my other 5870 everything works fine, tried to swap cards, use just one..etc but nothing, always this problem.
Any idea? What can be the problem?
What is your setup (H/W and S/W). I bought a 5970 off ebay few weeks ago, kept doing the same thing every time starting phoenix it would crash in windows and linuxcoin. Got fed up moved the card to a different motherboard and it works perfectly fine. Apparently that one board which already had 2x5850's & 1x5970 just didn't like him joining their crew, I have a 1200w PSU Antec so I know it could handle the power load.
Either way if you can test it on another motherboard that would confirm your suspicion, hopefully its not busted RMA'ing cards takes forever...
