Hi,

I just switched from win7 to win10 to be able to use the new AMD blockchain drivers among other things. I have a mix of 480/580/570 cards using claymore 9.8. I also use an autoswitching pool. I am experiencing a problem where my 8gb 480 card crashes when switching mining from eth classic (epoch 144) to eth (epoch 140). The other cards do fine during the new DAG generation but the 480 goes down and the miner/OS will lock up shortly thereafter. So far, the switching only occurs when the devfee wants to mine eth. All of the cards are mildly memclocked/uv and have previously been stable for days on win7/17.71/claymore 9.8. I have env variables set and 32 GB pagefile.

Unfortunately, my only solution so far has been to turn off the devfee - which I would rather not do. Any suggestions on how to fix this? Thanks
