Hmmm. 280x rig with 15.12 drives doesn't work, just HW errors. 470 rig with 16.9.2 works fine. Maybe it's possible to fix miner somehow? Maybe some people can't mine because of the older drivers?
I'm running R9 270x with 17.6.2 drivers and I can't mine, only get HW errors, so its not the drivers causing the problem
I don't know what causes the problem. 280x and 370 rigs with 15.12 drives doesn't work and 470 rig with 16.9.2 works fine. Maybe this is card specific. I'd like to point my other miners to the pool
