if ya core is propus, there's nothing else to be unlocked.

if ya core is deneb, there's 6MB L3 cache to be unlocked.

cache unlocking is same as core unlocking method, u need am2+/am3 board w/ sb710/750 & core unlocking capable bios.

as for oc question, read d stickies in amd oc thread. 

thats because the core is Deneb base and not Propus.

because if its show deneb then people would go for it instead of the propus base.

so the deneb base will be sold more than the propus based and that is costly to AMD and defeat the purpose of em creating Propus.

set unlock cpu = enable, acc = auto, if u can see 6MB L3 cache in cpu-z = deneb, if no 6MB L3 cache = propus. alternatively u can pop out d chip & check d code.

CACYC AC = Deneb
CACYC AD = Propus

u won't know whether ur gettin a deneb/propus core unless:

- u try to unlock it using d same method as core unlocking OR check d code engraved on d chip.

iirc, a deneb core w/ l3 cache locked will be recognized as propus in cpu-z.
