I know it's stable at 1.55v so that'll be my reference point.
What is your temps?

drop the CPU speed and raise your NB,you will get better performance.

My best guess is that Linux sensors software is not picking up correct values and the CPU gets overheated when running at 1.4v. It failed after ~4 hours.
On the other hand I should probably mention that it was the OS that crashed but none of the Prime95 tests failed.
I am, however, running a development version (Alpha) of Ubuntu and that might had had something to do with it. But then again, the crash dump clearly stated "HARDWARE FAILURE".

At VCore 1.55v, CPU-NB 1.3v, I'm hitting 55-56ºC.

Are they related? I mean, I get that the CPU-NB is the IMC and its inside the CPU, but dropping the CPU ratio will automatically let me bump my CPU-NB frequency?
I was under the impression that each one of them would only be stable by increasing the voltage (without taking into account memory, of course).

Haha, at least it's free and fully customizable
Trust me, if you're a developer as myself, once you try Linux you won't back to old BSOD Windows

I would go back to 4.0ghz. That means less heat plus a higher CPU-NB speed.
FYI
4.0ghz with CPU-NB of 2600 is faster than 4.1ghz or 4.2ghz with CPU-NB of 2400.

Yes, I got mine around here now and Iam happy as Larry with it, its where I wanted to get it to from yeasterdays stable OC, bring the ram up where it flies and the cpu/nb, I may take the cpu up higher when I work out better cooling but just to see what the chip will do. As it is now is how its going to stay......until BD that is

yes-that is they way it works.Once you start getting close to the limit of the chip,each setting will effect the other.Also the voltage,so if you can lower your CPU to 1.53v,you will get higher results on the NB.
