Core Unlocking

[bobob]

Hi

I have recently bought these parts below I have read on the Internet that some people have managed to unlock 2 extra cores on this processor. I have looked in the bios and have found a core unlock function is this the only thing I need to change in order for the 2 extra cores to be unlocked? I understand that it's best to run benchmarks on the CPU once they have been unlocked in order to make sure that the system is stable.

Parts

AMD Phenom II X2 555 Black Edition 3.2GHz

Gigabyte GA-MA770T-UD3



Please can you advise

Hi

Thanks for your response

One other question can this be done when windows is already installed ? Or do I need to reinstall windows in order for the extra cores to appear in windows ?

Ok thanks

For stress testing I normally use either intel burn in test or prime 95 are these still the best ones to use?

Many thanks

Hi,
Thanks for your further replies,

I am trying to unlock the other cores on the CPU and have gone into the overclocking menu on the BIOS and it displays the attached screen is this the correct place?

Also I have bought an XFX 5770 graphics card and I am having problems installing the drivers for that card I have gone to ATI's website and downloaded the drivers for that chip however they dont install. Do I need to get them from XFX's site instead?

Please can you advise,

Thanks

OK

Have fixed the the graphics problem had to change the display setting in the BIOS to PEG it was on PCI before and now the drivers have installed fine.

Here is the link for the picture I can view it okay from my end if it still does not work I can try uploading it again

Hi
Thanks for your reply.

OK, I have made the changes as below are these correct? Is there a risk that the CPU might get damaged in doing this?

OK,
Thanks for your reply.

I had a quick play around with it and the Windows 7 Welcome Screen lots of little squares and different colours, i have put it back on dual core and the issue has gone so I'd imagine that one of the extra cores is not completely stable.
