I'm too scared to try P09. I'm currently running on G25 and I finally got it rock stable @ 4.3GHz with a Vcore-load of around 1.42v. Going from P08 to G25 screwed all my overclocks and I had to redo them from square one. So.. I think I'm going to stick with G25 unless something listed in the change log persuades me to go through all the retuning again Hint hint :p
