I read on the forums about the problems of these video cards, the solution to the problems was in the BIOS firmware.
With a phoenix miner, these video cards work great, I have not tried other options.
I'm starting to think it's something in the BIOS, too.
Is it safe using phoenix miner? I've nothing against it, but I read that NiceHash cancelled from their list for safety reasons.
As @batsonxl asked, what's your driver version?
Thanks everyone for your help!
