While recently setting up my new AMD build, I read a section in the mobo manual referring to a feature called "core unlocker".
I brushed it aside at the time thinking it didn't apply to me, but after giving it more thought, I am wondering if it is feasible to use this feature with my mobo and CPU.
According to this article: http://www.pcstats.com/articleview.cfm?articleID=2490
The Phenom II X2 555 Black Edition uses the 'Callisto' core architecture, which is nothing more than a code name for the quad-core "Deneb" design with two cores disabled.
There was also a recent ZDNet blog post: http://www.zdnet.com/blog/computers/new-asus-motherboard-tries-to-unlock-hidden-cores-on-amd-processors/1711
talking about this new feature. They mentioned that "AMD does not officially support this feature".
Googling "core unlocker" brought me to another article: http://www.atomicmpc.com.au/Feature/171711,asus-m4a89gtd-pro-core-unlocker-actually-works.aspx
where the author successfully enabled 1 extra core (for a total of 3).
I've just gotten started with building my own computers, so I don't know much about these kind of tweaks or stuff like overclocking.
I'm curious to know if you guys think it is worth the trouble (and/or possible risk?) to try to unlock the extra cores in my processor.
