Ok, This has been on my mind that i came up with when i was at school.

instead of trying to understand it ,ill give you a example

Sempron 140 @ 2.7ghz

@ 2.7 the 2nd core is unstable.

But @ 2.5 the 2nd core is stable.

Phenom II X2 555 @ 3.2ghz

@ 3.2 the 2 other cores are unstable

But @ 2.8 the other cores are stable

Athlon II X3 455 @ 3.3

@ 3.3 the Last core is unstable

@ 3.0 the Last core is stable

So, if you chip isn't stable on a unlock would'nt underclocking might have a higher chance of a Sucessful unlock?

i thought so. But if this is some crazy theory (I come up with those a lot) Let me know.

Too bad i dont own a CPU that can unlock...

It is possible, but there is a chance the core is damaged and that's why it's locked. If you cannot get the core to post at stock speed (with a raised voltage) then chances are that's the case.

As a last ditch effort at a bit of increased performance you could try what you're suggesting though, worth a shot.

Good thought, it just might work, maybe the reason why amd ditched the cpu maybe cause it could not run at the advertised speeds. So underclocking may just work, to bad i got a good chip so i can't test this.

Anyone here has a defective core....PLEASE TRY THIS.
