Finally happy with latest 17.10.3 drivers (rigs are quite stable) with one exception - I use Claymore's settings for voltages and frequencies (not AfterBurner or something similar) and have to run it twice. This is because of low hashrate after first start for some cards - cards start with 23-25MH, but after stopping the miner and running it again they sdstart at normal rate. It is a clue for me.
I am on windows 10 FCU on using AMD 17.10.2 drivers on a H110 board with 6x 470s and 4x 570s. When I load Claymore 10.1 it doesn't accept my overclocks (I overclock from the config file not Afterburner) then it does accept it the second time I start it, if i ret restarting it a 3rd time it freezes my rig. Not sure if this is a Claymore of driver issue :/
