Having some weird issues with 9.8 + "blockchain driver" with 6+ gpu's.
Rig 1 (6x470) won't dual mine eth + dcr... it freezes / reboots / crashes. It mines ubq/music/etc + dcr just fine.
Rig 2 -- same issues. I added a 7th (470's) gpu today and now it won't even mine ETH only (can't create dag on random gpu #)
I don't think this driver is compatible with 9.7? I have no issues on other rigs that are 500 series.
