Well as I've been mentioning, I can't even bootup at more than 2GHz NB or over 9x NB multi since 4-5 days. It'll fail. No chance.

Volts/cooling makes no difference in my case. I've had the chip at 2750MHz 1.392V and switched it off and taken out the core in my hand 8 seconds after and it was cooler than my palm, far cooler than my RAM/HD/NB. I've booted 270HT ref. max with Phenom 9500, that's where the limit lies for it (low multi) and around 262HT ref. bootup at 11x multi. The board showed no vdroop/vdrop before but now shows quite a lot. 1.562V BIOS is 1.489V Windows idle. And AOD resets the voltages after you apply them to bootup values.
