Thanks for that Unclewebb, you're quite right. I always found I needed more vcore to pass P95 than linx on my Q6600, might be different on 45nm but I don't wanna run temps too high atm anyway.
Another good plus point about p95 is you can determine what voltages you need to increase if a certain fft size fails. Following that, I normally do a quick 1 hour test on OCCT to see if it's stable.
It can often give an error whilst doing this, but from that point it doesn't take too long to fine-tune the system, then I'll do a few hours in OCCT to finish. If I feel comfortable doing it, I'll give it a pew passes of linx too, but I'm gonna be very wary of it as I know 45nm are a little more fragile and I certainly dont want to fry or degrade the chip.
Currently at 494x8.5 to give 4.2GHz on 1.25vcore. This chip is chugging along nicely, will post pics when done
