Does anyone have an info on unlocking multiplier on Phenom II's? I've heard about core unlocking and cache unlocking so you'd think that it might be possible to also unlock the multiplier. So far the only info on this I can find is a single ocinside.de article on a single board. Does anyone know any more about this?

That was a freak chip in your link. He just got lucky it unlocked into an ES. You may never see another one in the wild.

Just found this article here, is it possible that there's more to unlocking multiplier than most people know? Seems like in this link it was all cpus on a certain mobo with a certain bios. If there's a way to reliably unlock multiplier on locked AM3 chips could mean a lot for things like 1 core records.

 

If such an exploit were to exist, it's extremely unlikely that it would remain obscure for all these years given the popularity of low-end AM3 chips among daily users and locked Semprons among overclockers.

There were several cases like that, I remember in AM2 era or maybe it was 939 when a lower multi CPU was installed after a higher multi and booted at it. I consider this a CPU bug pretty mich like the unlocked i5 3570 which was the last mention of such a "miracle". I don't think these are repeatable. But sometimes worth checking (unlocking multi on mobile Haswell with old CPU microcode).
