Hmm from what i have experienced with phenoms, they tend to have an upper voltage limit. Above you don't get it stable. So the top-down approach for overclocking will not work. Bottom-up is a long way if you really want to find all lowest voltages. Also knowing the lowest possible voltages does not help if you get in the idle freezing area, which seems to start at a individual cpu frequency.
I guess the fastet way is to test each core separate at say not more than 1.35V for B3's till the system starts to freeze idling and then use the multi of the weakest core.
During my first tests with the 9850BE it looked like the NB requires higher volts with higher cpu frequencies. This was a false impression it only took prime95 longer to fail with lower cpu frequency, so the nb voltage requirement is really independant from the cpu frequency. At 2.9GHz the system was alot more stable with a 2.4GHz NB frequency, but i could not get a stable 2.4GHz nb with a reasonable voltage (stopped at 1.4325V). So I think it's a good idea to test the capability of your nb first.



If someone finds a fix for the idle freezing I'd be glad to hear.
