I just had this start happening too, though i did just mess with my memory timings/frequency. considering the error message references memory locations (stack trace?) I think it'd be prudent for people to check their memory for errors and back off OCs if they are overclocked. However, seeing as it apparently happens agnostic to computer, maybe not. Still, it only just started doing this to me either before or immediately after logging in as I said and I've been playing for a total of 3-4 sub months with a 1070, so it's not a (solely) radeon thing.
