I happened upon a UEFI upgrade for my motherboard(GA-Z68a-d3-b3) a few days ago. Having only been use to the clunky(yet effective) Award BIOS, I was a bit apprehensive at first. But eventually, my curiosity got the better of me.
1. Made the bootable USB flash drive
2. Rebooted to the USB flash drive
3. Flash utility ran
4, System rebooted cleanly
5. Opened UEFI, set basic settings
6. Noticed that the VCORE offset is locked :angry: For those that don't know, I OC.
7. Sighed, saved and exited.
8. Reboot was clean and no hiccups, until the Windows login window popped up.
9. Res was 800x600 and keyboard and mouse were inoperable.
10. Knowing full well that the UEFI, itself, would not cause this, I proceeded to reboot the PC.
11. After a half an hour of reboots, the 1080p res popped up and the mouse and keyboard became functional
12. Logged into Windows to find that some very basic settings were undone and some programs were damaged
13, Oh, and the biggest PITA, had to reactivate Windows over the phone. For some reason, Windows recognized the UEFI as a new MoBo
So, just a heads up to anyone thinking about upgrading to UEFI, be prepared for some headaches. In the end, I lost control of my VCORE. Ultimately, this was not a big deal, as I am in the process of building a monster. As soon as finances allow, I will finish the beast and satisfy all of my OCing desires..
