I would like to add my voice to the growing chorus of others who have experienced a series of minor problems with the DZ77GA-70K.
I finished my most recent new build two days ago. It includes the components listed below , all new.
After loading Windows 7 Ultimate SP1, I downloaded and installed all relevant Intel drivers, firmware, and flashed the latest BIOS update; ver. 049. I did the same for the remainder of my new components, as well as updates from Microsoft.
I am experiencing the following minor problems that have been reported in this thread and similar threads for the DZ77GZ-70K.
- The two front USB 3.0 ports do not function
- I cannot access BIOS using F2 during boot-up
- The front LED indicator light constantly blinks
There are no error codes on the display. It simply reads '00', which, according the manual, means 'normal'.
I have carefully read the manual and all posts on the board related to this matter. Likewise, I have checked the BIOS settings using the configuration procedure. As others have stated, I am convinced that the problems that I've described are not directly related to hardware or BIOS configuration.
Other than the minor problems that I've indicated, the board appears to be very stable with no major issues.
Does someone from Intel read this board? Obviously, I would like to resolve these issues, which seem to be fairly common. If not, I can contact customer support directly, but I prefer not to waste time doing so if Intel is already in the process of addressing and correcting these issues.
Does anyone know if Intel is aware of these issues? Thank you.

Your setup is similar to mine, and I've experienced your problems. I have the Sonata Solo II case as well and with BIOS 0049 and proper USB 3.0 drivers installed I can get only one of the front panel USB 3.0 connectors to work, but the power LED blinks constantly. Disconnecting the front USB 3.0 ports from the MB header makes the blinking stop, so that's where I am since I don't have a pressing need for those ports at this time and I'm not sure what the blinking power LED is trying to indicate. I have a trouble ticket in with Antec about the USB 3.0 port issue.
I have experienced difficulty with getting the F2 to BIOS to be recognized, especially with Fast Boot enabled, but it is more of a timing issue and making sure you that if you have a keyboard that toggles Function Key Lock on boot that it is set in the right position. My keyboard is this way and during POST I keep toggling the Fn Key Lock and hitting F2 about twice a second to assure it gets recognized.
For what it's worth, I am on 0049 and have Fast Boot/General Optimization on without issues.
Thanks, Bobot. I really like the Solo II case.
I do not think the USB 3.0 issue we are experiencing is a physical hardware problem.
Everything that I have read to date suggests to me that the issue is related to the most recent BIOS release. Everything worked correctly in an earlier version of the BIOS, 039, but with the release of 045 and 049, issues materialized.
Typically, when I have a stable system and everything works correctly for a while, I do not flash to a new BIOS unless one is released for a specific problem that I am encountering. However, with a new board out of the box, I know that BIOS updates sometimes come along rather quickly for various initial problems. To that end, I like to ensure that the latest drivers and BIOS are installed early on. Later releases of BIOS firmware should not degrade or break a computer's performance, although we all know that it happens.
Anyway, these issues are not major, but I would like to see them resolved since they are certainly not unique to me or to you.
If a new BIOS that corrects these issues is not released within the next week or so, I will contact customer support and initate a trouble ticket, but I think that Intel is probably aware of them.
Minor problems with new boards are certainly nothing new and these are not a deal breaker. I think the board will be fine once these minor issues are resolved. To that end, it would be helpful if Intel would monitor their own community boards and let their clients know that they are aware of certain issues and are investigating them. Really, how hard is that?
dislikeyou, I've just tested that: the splash screen is gone, so I assume, that video optimization is working. However, I don't really see a difference in boot time with General optimization on and off. With those options set to on, I get that annoying blinking power-button. Gonna turn that option off now, until it gets fixed. I got some written exams in the upcoming days; gonna call Intel on July 30th and report my list of bugs (which is a huge list - probably gonna take several hours to explain and hunt them down on telephone). I don't know if it matters, but I will call Intel germany; which Intel support did you call?
Joseph - my board came with BIOS 0039 and IIRC, attaching the front USB 3.0 ports on the Solo II case to the board rendered ALL of my USB 3 ports unusable, even the rear ones. Detaching the front USB 3.0 cable from the board at least allowed me to operate the rears until BIOS 0049. Now with BIOS 0049 I can attach the front USB ports, but only one of the two works and the power LED blinks constantly. There is a known issue with pin 10 on the MB USB 3.0 header and some front panel connectors which I think BIOS 0045 was supposed to solve, but apparently there are still some issues. Maybe 0051 or 0053 will fix something for us? :/
Otherwise a good stable board so far.
I have same issue as you with Fast Boot causing POST to hang, not sure if both video and general or only video causes it. Good to know that i am not alone. Please go to Live Chat Support and report the issue. When i talked with them today i was told that nobody has reported the issue and that i am alone, so if you report it i will not be alone anymore.
I installed OS X Mountain Lion on my PC. It works, still not configured properly and checked if everything works. But i was surprised to see that it also shows power surge errors on the front USB 3 port. I thought that only Windows would show it. I will make a guide for installing OS X on this motherboard when i finish testing all stuff. It is legal as long as you buy Mountain Lion from App Store.
UEFI boot must be turned off. But i installed it using a usb stick and chameleon (it emulates EFI). You can install Snow Leopard to your PC or Virtualbox/Vmware and then from there buy and create a Mountain LIon install disk. I have found a working ethernet kext and for sound i used voodoohda (until i find a working ALC 898 HDA enabler for ML).
