Actually sleep is the only thing that works not reliable, at least not for me on a Z68XP-UD3 mainboard. I used the UEFI-Bios for some weeks and during this time I used "sleep" every day, the problem is that from time to time sleep fails or better to wake up the system. I would say 7 times of 10 it works but when it fails you have to reboot the whole system to get everything working. The biggest problem was that the network card does not work when the system wakes up… I tried everything, new sleep cycle, unload/load the kext, but the network card was dead only a reboot restored the card.
With the F10 Bios and DSDT sleep works perfect, every single day. Of course if you don't need sleep UEFI is nice, you can remove the DSDT file and then you have to reinstall the audio drivers for systems without a DSDT (check Multibeast for the option) and that's it. With a k-CPU e.g. Core i7-2600k you still need the SSDT but that's not a problem.
I personally need sleep for my system and so I switched back to the F10-Bios (Gigabyte tells you, that you can't switch back but that's not true , check http://www.techpowerup.com/forums/showthread.php?t=168667 for more informations about how to downgrade from UEFI) and now everything works perfect again .

UEFI has some issues.
The main issue I'm having is that my Apple ProRes 422 HQ files which are 4K are playing back with a fair amount of lag. I was wondering if it was possible to get it to playback smoothly.
Bios: Award F10
Graphics: XFX Radeon HD 6870 2GB
SSD: Corsair Neutron GTX 480GB
I installed Yosemite (fresh install) with Award F10 bios loaded. This is also the last time I've been able to complete the install process.
What I've tried so far:
1a. Trial 1: Installed Yosemite (fresh install) with UEFI bios already loaded
1b. Outcome 1: Constant hanging and freezing. Zero stability. However the files would play back extremely smoothly, like butter.
2a. Trial 2: Installed Yosemite with Award F10 bios and then upgraded to UEFI following successful Yosemite installation.
2b. Outcome 2: Constant hanging and freezing. Zero stability. However the files would play back extremely smoothly, like butter.
3a. Trial 3: Tried installing Mavericks with Award F10 bios
3b. Outcome 3: No dice, the installation freezes at the 17 min remaining mark every time.
4a. Trial 4: Tried installing Mavericks with UEFI bios
4b. Outcome 4: No dice, the installation freezes at the 17 min remaining mark every time.
Pretty low on ideas. Thanks for hearing me out. Hopefully you got some solutions.
I'm really curious as to what method you used to flash over to UEFI. Can you give me a step by step guide tomake the USB stick? I have the same board and I downloaded the U1j UEFI file.
I just want to get this done already. This such a good board I want to keep it running in tip top shape. I just want a clean install of Yosemite. Is it possible to migrate my applications from my cloned(leagacy BIOS) drive afterwards? How did the Yosemite install go after UEFI upgrade?
thanks for any help and good luck with your builds.
I also interested.
I am pretty late to this party, But here I go. I have a Z68 mobo running
Does this mean that the FLASHEFI.EXE file will just execute itself without any prompt from me?
Thanks for considering my questions.
I have never flashed any bios before and I know nothing about DOS. I am attaching a picture of the contents of my usb stick. Does this look right?View attachment 283053
