Is it possible? I heard that it is but it can be risky :/
So if it is possible how risky it is and what would happen if it failed?

It is disabled for a reason.
Probably because a core failed Quality Assurance testing and couldn't be sold as a 4 core chip. But rather than waste it and if the other cores were working then it could still be used.

If you hate bsods you should not try to unlock. It's not much risky if you manually set the CPU Vcore and CPU-NB voltages within limits during unlocking. At most your system won't boot after unlocking, but clearing CMOS should fix that. But know that unlocked core or cache has defects that you can detect much later, as I discovered almost 2yrs later. No stress test could detect that defect, in my case.
