Best STABLE OC on new retail 45nm CPUs?

[Capt Proton]

I want to comment on this,
Why do you think 8hours Prime is an indication of ROCK stability?

One might think that as it is pretty much the standard in most credible forums. There are also forums where people consider Super Pi as good enough. I, personally, do not possess enough knowledge to state categorically that 8 hours of Prime proves stability. I do consider it to be an acceptable test as I have read so many posts by folks that have a great deal more knowledge than I that say so.
What are your credentials?

There are application which loads Core2 much much higher than Prime, like Intel Linpack 64bit,
but even passing 100+ iterations in Linpack, which is really enormous task for Core2 especially on air, does not guarantee full stability in other application.

I do agree with this. I, personally have had a setup that was 8 hours Prime Stable (note I said Prime stable, which cannot be argued with) yet failed 3D MArk 06. Turned out my memory overclock was too high for 3D applications.

As a side note, then i see claims like 4+ Ghz with Q6600 or high 4.5GHz with newer 45nm CPUs, i know this is not really stable for sure.

Wow, now this is an emphatic statement. Only people with iron clad reputations and credentials should make statements like this. Please, let us in on your background so that we may judge for ourselves if you are correct, or just have an overinflated opinion of your own self worth.
