@particle: Sorry, I misinterpreted your post #17 in this thread:

I'm not a stability nazi by any means. Use whatever method you'd normally use for determining stability. The more time the better though. The more accurate the submitted numbers are the more the chart will help us determine overclocking trends.

I'd recommend as much stress mode on y-cruncher as you can stand with a minimum of 2-3 hours.
So i thought that 2-3 hours of prime would be sufficient. I will make a run on the next weekend with 8+ hours.

Btw my above settings are also stable with 1,225 VCore. Pretty nice so far on the cheap board.
