Who will be the kind soul to test the effects of 17.8.1, the AMD new WHQL? My rigs are stuck in a rental.
As expected, the 17.8.1 driver DOES NOT incorporate the Dag epoch hash drop issue fix from the beta blockchain compute drivers. So at least for now, if you care about mining ETH, stick with the beta blockchain compute drivers. Mining UBIQ which is not affect by the epoch hash drop issue had no difference in speed between the two drivers.
