I've P5W DH Deluxe and an E6600 running at 340x9= 3060MHz with stock volt, Orthos stable... and I want to go higher but, if i go any higher it results in BSoD :/ I've read the thread and I wonder if you guys have any tips for me?

The cooling isn't a problem, I've a Scythe Ninja which's cooling my E6600 and the temps is like, 25/40 which isn't bad? And yes, I'm running latest BIOS...

So, any tips?
