im using pooled mining with 3 cards on the same pc, and only the 5870 disconnects after some hours not the other miners. i also have setup backup mining so this should not be an issue.
its confusing.

Happened again last night. Clocks are at stock now.
I'm still not sure whether this 'disconnection' is something to do with the miner or the card. Is the driver crashing? Do you have another program that will stress the card which you can try running after a 'disconnection' to verify that the card is perfectly happy? Could you try different mining software for the second card?
Are you pool mining? If so, are you sure that you are not just disconnecting from the server? Perhaps try a different server or, better yet, solo mining, and see if the 'connection' problems persist.

I suppose this could be a feature of the mining software. I know hashkill has an option to stop when the GPU reaches a certain temperature. If you're comfortable at 70*C then you could investigate and possible increase this limit.
Myself, I found that at high voltages and very high clock rates that my cards will start running perfectly fine and then cut out when they reach a certain temperature. However, this was usually within 2-3 minutes, the exact temperature would vary slightly, and the driver would freeze (which I'm guessing isn't happening to you given that you said 'disconnect' rather than 'freeze' or 'crash').

ive had this exact thing, turns out when one of the cards reached high temps it stopped.
Both cards are at about 70o. Tried lowering the settings. Seems to be working now.
What the temps on the two cards? Have you tried lowering the settings on the card that loses connection?
My rig is running 2 x 5870 cards at 925/625. Getting 400mh/s. Problem is that quite frequently one of the cards loses connection. The other card keeps ticking away and the system is running fine.
Any ideas?
