Ok I have received the answer from Gigabyte.
Dear Nikola ,
Thank you for your kindly mail and inquiry. Don't worry that we just change it as BIOS controll so that there's no chip need to open Core boost.
If you still have any further question or suggestion about our products/service, please do not hesitate to contact us. We will try our best to help you resolve the problem ASAP.
Regards,
GIGABYTE TECHNOLOGY
So, after so much marketing about Core Boost technology, they just removed the chip and everything is on software now. But they still promoting Core Boost on 2.1 revision.
As I assumed, everything I wrote before is actually true!
