Prime95 stable at 3.73GHz; F@H stable at 3.60GHz--What gives?

[bipolar-folder]

I have a Q6600 G0 on 1.39-1.41V (load, idle). I'm stable with Prime95's blend torture test at 3.73GHz (415x9), but with the same voltage I can't reach stability folding until I drop the clock to 3.60GHz (399x9). (My temps are 58-62C under load and 37-39C idle).

Is F@H just that much better of a stability test? Or what's going on here?

Yes.

Think of it like this.

When your computer is F@H stable ... it is 100% stable..

F@H is one of the most demanding stress test you can put your system through.
