Updated 2 x S9's today with bitmains new asicboost firmware...
have been testing asicboost on bitminter for a few hours now with no issues..
packet capture and wireshark show its working.. slight decrease in hash power, 14.01 Th to 13.80...
I have not yet measured power to see what exactly the decrease in power usage is yet.
the miners seem to be running about 8C cooler than ones with original firmware so im guessing that is a good sign its saving power.
you guys may not know this but doc added the asicboost code to the pool back in April, just had to wait all this time to test it

Great Job Doc! It works!
