However, I was getting those stripe-lockup-screens whenever milkyway was running along with WCG (CPU DC app)
So I tried changing GPU clocks, different drivers etc but to no avail, same problem.
Then I increased CPU Vcore (don't ask me why lol) and voila, problem gone, I can now run MW and WCG 24/7 without problems. Weird thing is that I needed a rather huge increase, like 0,04V or so to make those stripe screns go away.
Again, without running MW@home I can run ANYTHING with 1,22V Vcore, prime, LinX, any game.
What can be derived from this is that maybe the 58xx cards are hypersensitive to CPU clocks, and will fail even though your overclock is technically stable. So try raising your Vcore I guess...
