Hello DjDafiDak, thanks for contacting us through the Intel Communities.
It is very important to let you know that we don't recommend over clocking any of the internal components such as memory, video or processor. This practice could decrease the lifetime of the processor and it could damage it. In addition to that there is no warranty support for that practice.
Since you have an unlocked processor, the BIOS will need to have the options to make the changes you are looking for. Therefore I suggest you to contact Gigabyte for additional information.
Thank you for your understanding.
