9 has some serious stability problems.

oh god. 8 was so much better than this. what happened?

I was experiencing same issues with V8 but with less rigs in total. V7 was way stable than v8 and v9

V9.0 has no stability issues! Your rigs do! Increase GPU voltage or lower clocks!

this actually helps

even a broken clock is correct two minutes out of every day

referring to the forums signal to noise ratio more rather than Preludes track record of course..
