I'm sick to death of my miner crashing.  I have six rx 470 8gb sapphire cards and it can run ok for days, then locks up.  Then I have to restart it about 10-20 times because I constantly get the message "Ethdcrminer64.exe has stopped working".  Then I go into GPUZ and see that one of the cards is not reporting data fully.  After 10 restart or so it starts working again, and I get a few more days mining,  sometimes less.

What could be causing this?  All cards are cool, well ventilated running at 74 degrees contant.  this issue is really pissing me off now. All parts are relatively high quality,   EVGA power supply etc.

I am running win 10 64 bit
