Note that the dag cache isn't implemented in 1.27 for amd cards, so when you mine eth+zil you loose 2 dag generations every 90 minutes. A few percent. This is fixed in v1.28
For the moment I am to excited about that 67 Mhsh seeing in the miner and I am staring at the Anydesk from almost half hour now.I don't even have a new motherboard with BAR option to give another boost otherwise I believe I would be seeing 75 Mhsh without problems here.I will update in due time to the new version,no worries about that.
Hopefully it doesn't crash after sometime like all other miners.
You should stop mining if you still haven't figured out how mining works in years ...
What gives your performance, stats as always on 1 million shares?:
