I have had a rig running 0.5 for nearly a year with no problems 5x MSI Gaming X 1070 on Windows 10.  One of the cards died and I did an RMA.  They sent me a Gaming Z 1070.  When I put that card back in I now get this error for every card.

09:50:22 CUDA: Device: 0 Thread exited with message: "an illegal memory access was encountered"

And a popup for windows 10 says this.

"Application has been blocked from accessing graphics hardware."

I then upgraded to 0.6, nothing changed.  I googled some and figured since the RMA card I got back was different I then should just set every GPU back to stock using MSI afterburner.  That didn't fix it either.  MSI afterburner says driver version 388.13.  I then used windows to update the drivers to 399.24 and that didn't fix it either.  Next I used DDU to remove all drivers and start from scratch and that didn't fix it.  Ugg.


I have ran out of options.  Any ideas?  Thanks,
