New UEFI updates for Gigabyte's high-end Z77 boards

We know some of you are having some slight problems with your builds and as we've pointed out in the past, this can be related to the BIOS/UEFI, especially if you're using a new motherboard. Gigabyte's 7-series motherboards have only been out a couple of months and as most of the boards are shipping with an early UEFI release, the company is issuing regular updates and a wide range of boards have received multiple updates in the past couple of weeks, so we thought we'd highlight this once more.

The boards in question are the GA-Z77X-UD5H, GA-Z77X-UP4 TH and GA-Z77X-UP5 TH. In this case the GA-Z77X-UP4 TH was sitting on release F4 for a very long time, but Gigabyte has removed that version entirely from its website, so it's pretty clear that there were some issues with this UEFI update. The latest version is F7 at the time of writing which was released a week ago. The release notes are fairly uninformative, but the F7 release is meant to improve system compatibility whatever that implies.

The GA-Z77X-UP5 TH is already on version F9, although F5 through F7 are missing here. We should also point out that the earlier release for both the GA-Z77X-UP5 TH and GA-ZZ7X-UP4 TH added some improved graphics card compatibility fixes. The slightly older, but more affordable GA-Z77X-UD5H has already reached UEFI revision F14, although here we once again have a gap from F8 all the way to F13. This board should feature the same updates as the previous two models.

Note that Gigabyte's UEFI and BIOS updates come as a self-extracting 7-Zip Windows executable package and as such you need a suitable un-archiver for OS X (Stuffit Expander works) if you don't have a dual boot system. The UEFI update needs to be copied onto a FAT32 formatted USB drive and you can then use Gigabyte's Q-Flash updater from within the UEFI itself to update your board. We highly recommend doing this, as it's highly likely to fix issues with your CustoMac, although we haven't had a chance to test the latest releases just yet, so you want to play it safe, you can wait until we've had a chance to do some testing and report back. However, it's always possible to flash back to an older UEFI or BIOS, so it shouldn't be a big deal.

I just checked Gigabyte's page for the UP5 TH and was surprised to see so many new BIOS updates. I think I'm still on F4 or something. I'll test this one in a few and see how it goes. I hate BIOS updates! Always nerve-racking.

Did someone tried F14 on a Z77X-UD5H Board with ML?

I am still running F8.....

Anyone know if this would possibly fix the Audio problems on the UD5H?

I was having a variety of problems setting up my build with the GA-Z77X-UP5 TH. Ran the update using QFlash and everything installed nicely and now works great.

I tried doing the update to F14, but when I go into QFlash, only one drive pops up as a choice to select from, not my usb drive or my second (windows) hard drive. Anyone know why?

Did you format it to MS-DOS?

I just updated to F14. All seems fine.

Just use @BIOS to update automatically on windows

I just updated my GA-Z77X-UD5H BIOS and it appears that all of my system settings have been reset to defaults. However, I did just begin using Time Machine too...so who knows which it is. This is my first time updating a BIOS.

I just updated my GA-Z77X-UD5H. My first time updating a BIOS. It looks like my system setting have been completely reset, even the new version of ML got rolled back...weird. All my files are still here though. Is this normal?
