I been having too much trouble with mining with AMD GPU miner.  ID problem, duplicate shares, compute error, crashed gpu, rig hard crash etc.  Been trying to scale back setting to see if it helps, but overall too much trouble.  Needs constant baby sitting.   Moved GPU miners to something else already.

Monkins latested amd miners don't actually mine even though its registering decent hash rate.  No shares are ever accepted on any intensities.  

On side note, Webchain probably will see higher value if its kept CPU mining only, which will also enable web mining to be somewhat more productive.  Just saying.
