OC'ing to unlock hidden cores...

[CompGee]

Hi, everybody! I am wanting to overclock my CPU to unlock hidden cores to help make my system run faster. Does anybody know any way to unlock those hidden cores? Thanks!
NOTE: Going to be updating CPU-Z signatures soon.

How to unlock...

Now I would not over clock your system if you do this. Those cores are unstable hence the reason they are locked.

What CPU do you have? Only a few can be unlocked and there is no guarentee that those cores will work. On the Phenom II's it was about a 20-30% chance of getting a bonus core.

Will depend on what cpu you have and if your motherboard supports core unlocking.

As far as I know you can't unlock cores on intel cpus, a select few amd cpus can be unlocked but it is never a guarrentee they will function correctly.

I wonder if Intel actually physically cut the extra cores with a laser like they use to do with the old 486 SX chips when the cut out the floating point processor. I guess not. Sorry for going off topic.

I believe that they're locked out in non-reprogrammable microcode, in the same way that Hyperthreading, various instruction extensions and the extra cache is disabled.

I have a Gigabyte motherboard with a LGA2011 socket. I also have a Intel Pentium D CPU with 2 cores. My BIOS revision is F2. Is that enough?

 

[hunter315]

A Pentium D is an LGA 775 chip, it won't even fit in the board, let alone run.

A pentium D also only has 2 cores, so what would you unlock on it?

 

[CompGee]

I meant LGA775.
