UEFI upgrade for GA-Z68X-UD3H-B3?

Recommended Posts

Hi, I'm wondering if there is a straightforward way to upgrade to UEFI? I have bios F12 on my GA-Z68X-UD3H-B3 and am using 10.8.4. 


Is there a guide on what changes have to be made for an existing system?

Is it worth the trouble to update? I currently have:

working usb 3.0
working sleep

Other specs:

Gigabyte 6850 graphics card
Syba 1394b PCI Express card

we can't say that you will not have errors.


but in some cases, some have not had bugs. it is possible to downgrade, if you have any problem.


BUT do at your own risk.
