6xR9 380 periodically resets GPU0 speed, and the miner errors appear non-existent cards, with which it can be connected?
It's a bug, will be fixed in next update. Divide card number by 2.
How soon will be next update ?
Do you want more speed?
I got 4x480 on some of my rigs and one GPU shows 0 but with load 100% and heat. This is not so good, right ? I guess everyone wants more speed or what do you mean ?
1. It's strange and can be related to some hardware problem.
2. You will be surprised, but not all people want more speed, though it puts CPU botnets to nowhere.
Agreed, more speed puts the botnets out of business.
