Again, temps are pretty much identical on both cards, and were still the same when the second GPU worked at full. With Claymore Cryptonote miner both were running fully, but there's no new releases that support v8. I don't know what's the issue, it seems so random. First Windows update made it working correctly for several minutes…. Then the BIOS update for a couple of hours. After that initial window its the same story again. My last resort is reinstalling the Windows again.
